Brian's Stickman Reproductions



Brian Pletcher, the original puzzling super-blogger, has been jolly industrious recently. He challenged himself to produce 3D printed versions of a pair of Robert Yarger’s iconic puzzleboxes. You can read his story over here.

A couple of my mates had bought copies of the Borg Box from Brian and some of the guys on the puzzle forums were raving about them. I’d pretty much decided to get myself one when George Bell put up a photo of his colourfully dyed copy and that absolutely sealed it for me … and with the looming Shapeways price increases I managed to squeeze in an order just before they virtually doubled in price. 


Brian being a rather generous soul ended up tossing in a free copy of his version of the Snowflake as well and a couple of weeks later a pair of rather stunning little reproductions arrived in Barnt Green. 


Now in the interim, my mate Adin (the origami-guru and designer of evil exchange puzzles) had also bagged copy from Brian and was planning on dying it so it wouldn’t be plain Shapeways white (albeit strong and flexible!).  Thinking that tossing an extra set of pieces in the pot wouldn’t be a lot of extra bother, I asked if he’d mind adding mine to the brew and he readily agreed…. Only, a few days later he’d put up some pics of his copy resplendent in glorious Technicolor and I hadn’t even dropped my white bits off at his place yet… so much for not much extra bother. 


Long story short, Adin merrily dyed my copy a couple of weeks later and then dropped off a set of colour-coded bags of bits when he and Sophie came round for a day’s puzzling… along with a few other puzzlers. 


So while Adin and Chris were both still there, I tipped all the bits onto the dining room table and set about trying to work out how the heck to put this puzzle together – remember Stickman himself charges a hefty assembly fee to anyone who takes their full-size copy apart and can’t get it back together again themselves. 

The only time my original copy has been apart was in the hands of my expert puzzle-solving mate Louis – and even then he took one panel apart at a time and kept the pieces neatly laid out in order… 

I was faced with a  pile of scrambled bits – and even with the full-size copy next to me for inspiration (and reference) I really struggled to even start to see how it went together… With a lot of encouragement and advice from Chris, I managed to make a bit of a start but we had to call on Adin for some help once we had the panels more or less together... at which point we realised some of the locking mechanisms needed to be reversed in order to get the panels to actually go together. 


It must have taken well over an hour to finally get the little marvel assembled and locked up… so now whenever anyone opens my Borg Box, they will find a rather colourful little 3D-printed miniature version inside it… :-) ...and when they open that copy... it's empty... but wouldn't that be pretty cool... turtles!


…and since Brian had sent me a copy of Snowflake as well, and it just so happens to fit perfectly inside my Snowball, anyone opening my copy of the Snowball will find a neatly nesting copy of Snowflake inside that as well!


Thanks to Brian to letting me get a copy before Shapeways’ prices went skywards and for tossing in the Snowflake as well – and a huge THANK YOU to Adin for boiling some colour into my little Borg Box – it looks brilliant!

Friday evening - IPP Banquet


The Friday evening banquet was a slightly more formal affair than the Founder’s Reception the night before ... instead of milling around and chatting to one another with buffet tables around the corners of the room, we now had a couple of tables of Renegades and their partners. We were a bit late in getting in, so we ended up at a couple of tables next to the door – which ended up working out quite well when they announced the buffet tables outside were ready for us – we were near the front of what ended up being a really long queue for the grub.

We had a great bunch of folks at our table – we wound up sitting next to Kellian and Brian and had a great time getting to know them and hearing about the dancing scenes in various cities as Kellian and Lesley swapped stories about their dance endeavours.

The organising committee had left some puzzles scattered around the tables and I ended up spending a lot longer than I should have solving Markus GoetzRhombus Flexing puzzle – in spite of having done it at home a while back!

Lennart Green performed some amazing close-up magic with the help of a couple of huge video screens on each side of the stage. Wil was telling me a bit about Lennart Green a couple of days later – it turns out he’s totally self-taught so all of his sleights are unique and aren’t what you’re expecting, making him very much a magician’s magician. Some of his work was absolutely incredible (in both senses of the word!) and I really enjoyed his show. 

Unfortunately the magician who followed him wasn’t quite in the same league (technically or presentationally), but afterwards Peter’s mini bar key came out again as Kellian & Gill hadn’t seen it yet (and he was much better than the last bloke on stage). Having totally fooled her with the magical roaming chain, Kellian asked if she could inspect the key chain and without missing a beat Peter pointed out she was a married lady and that wouldn’t be proper! Superb!

After the formal entertainment was over, folks began milling around and a couple of tables of magic appeared – Todd Reis brought out his bananas again and Lennart Green sat down with a more intimate setting – about forty people crowded around a single table craning for a good view of the action – he didn’t disappoint!
At one point I wandered over to a table piled with twisty puzzles where a bunch of the twisty cognoscenti were deep in discussion – only to have my way barred by Rox telling me I couldn’t hang out here as I “wasn’t twisty enough!” – before dragging me over to show me something interesting on the table! While I was there James came over to demonstrate something that Oskar had showed him earlier: a cube where the opposite sides are connected by a gear train – except that depending on where in their phase the gear train is positioned, the effect on the opposite side is different ... e.g. moving the top layer half a twist moves the bottom layer a half a twist – so far so good – moving the top layer another half a twist moves the bottom layer a quarter twist – HANG ON! The next half twist inspired a full twist on the opposite side... now before you ask, no I hadn’t been drinking – that freaked me out more than a little!

After a while I wandered back down to the puzzle room where the hard core puzzlers remained. I had a serious attempt at Mike Toulouzas’ Vault and managed to solve it – it is a serious piece of art – a beautifully crafted wooden puzzle box that looks and behaves like the real thing it’s imitating. At first I was a bit confused when I’d discovered more tools than I thought I had a use for, until I tried closing the box ... turns out they weren’t red herrings after all and closing the box is a seriously non-trivial exercise! Superb work Mike – I love it.

I managed to solve the Double G puzzle – I really hope that someone picks up the rights to produce these, it’s a great puzzle. It looks really simple but those little tabs manage to find all sorts of ways to block everything that you’re trying to do... a masterpiece of simple, subtle design.

I had a play around with Jane Kostick’s Double Duals and enjoyed playing with this one as much as all her other puzzles – if not a little more. This one comes disassembled with very little clue to the eventual shape and once you’ve worked out which sets of pieces work together you can assemble one set and then add the other set – although it doesn’t matter which order you do it in ... hence the name – either set of pieces can be on the inside or on the outside ... she’s pretty clever with her geometry is Jane.

While I was playing away with a variety of things Robert Yarger was thoroughly investigating Jerry McFarland’s BurrBlock – he spent ages playing with it and examining all the bits as it came apart, and then the next day he and Jerry had a long chat about it .... he seemed pretty impressed and definitely seemed to be enjoying the challenge that night.

Chinny sidled up to me at some point and asked if I had one of his wobbly tops yet. When I said I didn’t he promptly gave me the last one he had, and when I offered to pay for it he refused any offers of cash and insisted that I buy a lathe and make three wobbly tops and give them away. Now anyone who’s seen these little marvels (mine’s about two inches tall) and understands the mechanics of using a lathe, will know that Chinny is both a master lathe-crafter and a little nuts! Having seen some clips of off-centred lathe-work with a chunk of wood spinning around trying to throw itself across the room at the craftsman, I’m pretty sure I won’t be trying that any time soon! Yet here’s Chinny giving me a beautifully made wobbly top, complete with decorative chattering and his trademark whistle in the top...

When we asked him about his off-centre lathe-work he replied “It doesn’t terrify me any more!” – I’m not sure I should believe him!

He hauled out a bunch of other little treasures that he carried around, including introducing me to La Boomba! Looking like a classic cherry bomb, this one is turned from coloured pencils and once opened it begins to tick loudly before letting off an explosion, all the while a menacing-looking Lego mini-fig glares at you ... that’s the sort of thing to expect from Chinny – he’s an absolute scream and it was wonderful to get to spend some time with him that night. Cheers mate!

Judge's Gavel Puzzle


Judges have cool toys.
I first noticed Mike Toulouzas’ Judge’s Gavel in the entries for last year’s Nob Yoshigahara Puzzle Design Competition on John Rausch’s web site – and soon after the end of IPP31 spotted that it had been awarded a Jury First Prize Award … and then a couple of weeks later I really enjoyed reading Brian Pletcher’s descriptions of his experiences with the various competition entries – and the one thing that made me smile was his references to the loud “THWACK!” whenever anyone was working on Mike’s Gavel.
Toward the end of last year, I’d been swapping emails with Mike about another of his puzzles and I mentioned in passing that if he ever made another run of Gavels, I’d love a copy, and then promptly forgot about that for a couple of months – during which time I found myself playing with a copy at Peter Hajek’s place and thinking to myself that it really was a rather cute puzzle … so when Mike got back in touch a few months later and said he had some available if I was still interested … it didn’t take long to Pay(pal) the man and take receipt of a nicely packaged block and hammer!
The new run is, I suspect, a little smaller than the earlier run (and I’m going on my recollection of the size of the Gavel on Peter’s bookshelf back in December – so I may well have that wrong!) and has had a neat brass plate added to the block that proclaims “Judges Gavel Puzzle”. The block is made of Lignum Vitae – that super dense wood that actually sinks in water, and the Gavel is made of a combination of Mahogany and Mexican Ebony. The shaft of the gavel has a trapped ring spinning loosely around it and your goal is to free the ring … the only strange thing you’ll notice more or less straight away is a small hole on one side of the head of the actual gavel.
You’ll probably be tempted to try unscrewing the handle from the head (yip it spins pretty freely – although sometimes it seems even freer!)  or even unscrewing parts of the head itself – and they won’t get you far. At some point your inner child will get the better of you and you’ll have a bit of a “THWACK!” and you’ll find that quite satisfying and you’ll probably have a few more goes before you get to wondering if all that thwhacking might actually even be useful – result! – A puzzle that encourages you to play like a child!
Brian’s original description got it spot on – what makes the puzzle great is that it’s very gavel-ness is central to the solution of the puzzle – and that’s very satisfying.
Mike’s lathe-work is expert. The gavel absolutely looks the part and you’ll have no qualms about giving it a decent tonk on the supplied block – if it weren’t a puzzle, it would still look great – knowing it’s an award-winning puzzle as well makes it something really special. 

Thanks Mike – it’s brilliant!

Neil's written about his thoughts on the Judges Gavel over here as well...

Four Colour Map jigsaw


Mathematicians like colouring-in! 
There, I’ve said it … now let’s see if any of them read this blog and feel the need to agree or complain…
According to Wikipedia, the less formal version of the Four Colour Theorem states that “given any separation of a plane into contiguous regions, ... no more than four colours are required to colour the regions of the map so that no two adjacent regions have the same colour”. Which is fine if you’re a mathematician – I think it means that you can colour in any flat map (drawn anyhow you please) such that each enclosed area is a different colour to all of its neighbours, using only four colours … and before you hit the comment button, I know that’s not nearly rigorous enough for a mathematician, but I suspect that it works just fine for the other 99.9% of us.
That particular little puzzle had fascinated mathematicians for ages and was eventually proved by Appel and Haken in 1976 using a combination of brute force computing and good old-fashioned analysis on paper … which is an awful lot of background, but as I’m not usually a big fan of jigsaw puzzles, I thought it was important, if only to convince myself that this wasn’t just any jigsaw puzzle – it was really a demonstration of a mathematical theorem – and that makes it OK!

I first stumbled across this rather interesting jigsaw puzzle when I read Brian’s blog about the puzzle over here – the idea of a jigsaw puzzle with no picture on the face of it, where no colours ever join up, and pieces that are just plain whacky, was more than a bit appealing. I duly followed the link across to Artifact Puzzles and was more than a bit gutted to find a wonderful selection of interesting jigsaws (yes – they looked intriguing enough to interest the non-jigsaw-lover!) being offered by a company that would only deliver to the USA … and I’m on the other side of the pond. Dagnabbit!
It seems that this same experience had struck one or two other folks “over here” and a few months later puzzling-buddy Louis asked if anyone was interested in one of these puzzles after he’d convinced one of our American connections (The Juggler!) to play middleman and send them across the ocean – in a mate’s luggage as it turned out … and in the end about six of us were able to get our grubby paws on a copy of this great little puzzle, and then Louis wouldn’t even let me pay for mine on the grounds that I was providing board and lodging for his last trip to MPP5 – thanks Louis!
It comes in a drawstring bag and has a small picture of the assembled puzzle stashed with the pieces – don’t pay too much attention to that and you’ll enjoy the puzzle more – trust me.
A quick look at any of the pictures will show you that the pieces are different – very different! They’re literally designed to stretch the four colour theorem in lots of ways and as a result you have some unusual joints – including a few places where you’ll find more pieces coming together than you’d originally expected – and yet you’ll never find adjacent pieces with the same colour … and yes that’s useful, especially once you get going.
Being the horribly organised type, I sorted the pieces by colour and then set about trying to find obvious joins. (In fairness, that was the only way to start it since there aren’t any straight edges or pictures to build up!) Once you have a couple of pieces together, you can narrow down the piles that need to be searched for the next pieces to add on by eliminating touching colours – and that’s generally a good strategy, but as I said, every now and then the shapes of the pieces throws you a curve-ball and the single piece you’re looking for turns out to be a combination of two or more pieces.
It took me the best part of an hour and a half (and a cup of coffee) to complete this little puzzle – and it only has 68 pieces! And I really enjoyed it, even though it’s “just a jigsaw puzzle”. In fact I’d probably go so far as to say that if you were only going to admit a single jigsaw puzzle to your collection of mechanical puzzles, this would be a pretty good candidate.

Havana’s Box II – “Heather”


The second in Eric Fuller’s series of cigar boxes had me stumped for quite a while. There are a couple of relatively obvious things to do to it at the start, and I did them all, but then I found myself at a bit of a loss – the lid would open an inch or two, showing you that there was a cigar in there, along with a couple of matches that could be tipped out, but try as I might I couldn’t find anything else to do … so it was placed on the “To be solved, damn-it!”-shelf on the desk and every now and then I’d take it down and try something slightly different in the hope of stumbling onto something useful (OK, quite often I actually tried exactly the same things hoping for a different outcome … and I know that some clever bloke had some opinions about the wisdom of that approach!) .
OK, the box is made of Sapele and is named after the “one of the friendly part-timers behind the bar” according to Eric’s description – mine has a bleached Lacewood veneer on the top and bottom. It’s supposed to be a step up from Chris and I can certainly vouch for that!
I’d read Brian’s blog about the box and took his warnings about not shaking and bashing the box for fear of finding an ‘alternative’ method of opening it …although I did try doing exactly that, just a little, anyway – and had no success at all. 
I kept getting to exactly the same place every time – 3 moves in and hit a dead end! I’d tried shoving the matches into the various grooves on the box (surely it couldn’t be coincidence that they just happened to fit in those grooves perfectly?!) – I tried poking around inside the lid of the box with a match – I even thought there might be magnets hidden inside the matches to release a catch somewhere (hey, I was getting desperate!) – I had noticed that the ends of the matches had been ever so slightly rounded … so I was sure they were key to the solution, but I couldn’t find anything useful to do with them…
So I did the obvious thing, and left it out for Louis on his last visit – he’d solved it by the time I got up the next morning – how’s that for service!
All was clear – and I’d been totally fooled – the mechanism is neatly hidden and had eluded me for weeks … in my defence, the first few moves send you off in entirely the wrong direction.
I like the fact that once opened, you can actually remove a few of the panels entirely, and see just how Eric has got some of them to behave the way they do – he is quite clever with those little things!

Peter Hajek’s End-of-Year Puzzle Party (EPP)

The first time I heard about Peter’s EPPs was when I picked up a copy of a colour booklet called “The Best Puzzle Finds of the Year 2009 / 2010” from Wil Strijbos back in October. It’s a soft cover 60-odd page booklet documenting a collection of puzzlists presenting their best three puzzle finds of the year – with quite of few of them attending the EPP at Peter’s house at the end of 2009 and 2010 to share their finds with others.  I was delighted to have come across the booklet as it contained several puzzles I recognised, some that I already have, and a number on a wish list for “one day when I grow up!”- all of them described by people who were enthusiastic about them and considered them one of their three best puzzle finds of the year. What better recommendation could you wish for? 

Wil in action
A little while later, Peter sent out an invitation on Nobnet for contributions to this year’s selection, and also invited anyone who’d be in London at the end of December to come along – I decided this was way too good an offer to refuse, so set about choosing my 3 three puzzle finds of the year to email off to Peter – and made some enquiries about going along on the day ... Peter was really encouraging and as it turned out, Gill and I were going to be in London that day to see some friends from South Africa who were over on holiday, so I made arrangements to attend. 

I was one of the first to arrive on the day – not counting Wil and Joop who were staying there – but pretty soon the place was filled with puzzlists wandering around peering at the crates of puzzles for trade / sale, chatting about our nominated puzzles and picking up and playing with the odd puzzle dotted around the Hajek house. 

David Singmaster with his prized find
Peter played the perfect host and made sure that everyone had been introduced and given something to drink before allowing us to mingle and get to know one another for a while ... given that Wil was the only person there that I’d already met, I ended up meeting a bunch of new puzzle-fiends, and a couple of magicians (Peter doesn’t discriminate!). One of the gents I met comes from just down the road from me – and it turns out is a rather accomplished designer of puzzles – although to my shame I only discovered that afterwards – hopefully I’ll be able to convince Sam Cornwell to come along to one or two of our MPPs in the near future – I know there are a few people who’d like to meet him!

Peter always manages to arrange for a lecture or a performance of some sort during the afternoon – in 2009 and 2010 there were a couple of magic performances and lectures from Laurie Brokenshire, William Houston and Angelo Carbone. This year Peter had lined up artist Patrick Hughes to talk about his mind-blowing perspective-mangling art. I hadn’t come across Patrick’s work before so did a little Googling beforehand and read up a little but it didn’t really prepare me for what I was about to experience – Patrick had brought along one of his works (“Volumes” 6/7 from memory) and had it displayed up at the front of the room – he gave a wonderfully self-effacing talk for someone who was clearly a very gifted artist from where I was sitting and talked about how he found art that challenged your perception or your assumptions really interesting, mentioning a couple of pieces of others’ art in his own collection to illustrate his points – then he turned his attention to the piece he’d brought along and started describing some aspects that,  to be honest, didn’t make a lot of sense to me given where I’d been sitting (toward the back of the room). He’d been talking about how the piece seems to move in unusual ways when you moved across it and that this was partly the result of your brain trying to make sense of something that didn’t really make sense because of how it had been painted – he’d illustrated the concepts earlier by talking about the Ames Window but I was having difficulty linking those ideas with the painting I was looking at, or rather from where I was looking at it. 
Patrick Hughes

At the end of his talk, Patrick encouraged us all to experiment with his painting and when I wandered up close it made sense all of a sudden! What I was looking at wasn’t a flat painting, it was a painting on a series of projections where the painting had been given a forced perspective – some of which were right (i.e. exaggerated) and some of which were wrong – so as you looked at the painting your brain tried (unsuccessfully in my case!) to make sense of what it was seeing, forcing one interpretation on it – which was fine, until you moved – up or down or left or right – then the combination of forced perspective and actual projections caused things to move in a way that your brain wasn’t expecting, helpfully (!) your brain then tries to compensate and tells you that the things in the picture must actually be moving around in a rather strange way ... a very spooky effect indeed! Several times later that afternoon there’d be three or four of us standing in front of that piece swaying sideways or bobbing up and down and remarking about how weird it was. Patrick is clearly a master of perception and knows just how to toy with it to create some really disturbing effects – and I’m glad that I’ve been introduced to his work – not sure I’m ever going to be able to add any of it to my collection, but privileged to have been exposed to it by the man himself. 

After Patrick’s talk and a brief break, we each took turns to present our three best puzzle (or magic!) finds of the year ... we took turns alphabetically and managed to tie ourselves in knots once or twice and promptly rearranged the alphabet but managed to get all of our turns taken in the end. 

I’d nominated Brian Young’s Opening Bat, Robert Yarger’s Little Game Hunter and Coffin’s Rosebud made by Scott Peterson as my three puzzle finds for the year: 
  • Opening Bat because it is an epic puzzle that keeps you going for ages and then rewards you superbly at the end when you solve the final part of the puzzle,
  • Little Game Hunter because I managed to get one straight from Rob after starting a small collection of Stickmen earlier in the year and getting yards and yards of advice and encouragement from Rob while I was finishing off my DIY Chopstick box and the Grandfather Clock – I love his puzzles because they’re all so entirely different and each presents a unique challenge,
  • Rosebud because it’s an iconic Coffin design and it was both my first puzzle from Scott Peterson and my first taste of Coffin’s unusual geometry – both of which will hopefully stay with me for quite some time!
It turns out that someone else at the EPP (Steve Nicholls) had also nominated the Opening Bat, and in fact, so had 6 other people who’d provided email submissions – making it the runaway best pick of the year with a total of 8 nominations! The previous record for multiple nominations (shared by the Stickman Gordian Knot Box and Oskar’s Gear Cube) was four nominations, back in 2010. Peter reckons the record is likely to stand for a while – I reckon it reflects what an incredible creation Brian came up with...

After the presentations Peter and Katja provided a tremendous spread for dinner that kept us going for ages before we inevitably lapsed into more puzzle chat, bartering and outright buying. 

At one point Peter called me to join a couple of others who wanted to see his puzzle room upstairs – there were a couple of us who hadn’t see the puzzle room before and the first puzzle turned out to be how to get into the puzzle room! The door appeared to be locked, with a keyhole on the side where you’d normally expect it, and a handle not quite where you’d expect it – helpfully there was a key supplied, unfortunately it was rather well attached to a chain on a hook in the middle of the door, and wouldn’t you know it, the chain was too short to allow it into the keyhole ... and it kept us out until Peter helped us out and showed us in ... WOW! The puzzle room houses an absolutely stunning collection, most of it beautifully displayed in glass-fronted cabinets ... from a number of early Stickmen, through the genesis of the Karakuri Group, via an exceptional collection of Kamei’s and onto an impressive set of Coffins, key-chain puzzles a-plenty (even though most of them are in the cabinets of drawers) and best of all (for me at any rate) a collection of Trevor Wood boxes, including Takashima’s Tantalizing Temple in pride of place ... lovely.

Back downstairs Tim Rowett did the rounds dishing out Christmas presents to everyone and telling stories about each of the little goodies he was handing out and somehow didn’t seem to tire of telling them – everyone got the same treatment whether you were first in line or last...


Slowly the numbers dwindled and we were hit by a sudden realisation that we’d missed the opportunity to take a group photo before folks started leaving, so we ended up with a slightly depleted group photo – maybe next year we’ll be more vigilant... 


While things wound down, we naturally found ourselves gravitating toward the study where everyone managed to find something interesting to play with or discuss – me, I found a recent little Mike Toulouzas creation that I hadn’t seen in the flesh before and enjoyed solving it for the first time – and I managed to do it quietly, unlike the majority of the folks at the last IPP who seemed to make quite a racket playing with it judging by Brian P’s account.  I can see why it won a Jury First Prize award though...


In the intervening weeks Peter has been beavering away and has already sent us all  (including those who emailed their selections) a soft copy of the booklet – complete with write-ups and photos – he is incredibly efficient ... as well as a tremendous host!


Thanks to Peter and Katja for opening up your home to a bunch of puzzlists, including a number of unknown quantities like myself who came along for the first time, for making us all feel at home and giving us a great day (and night’s) entertainment – your hospitality was supreme! 


And finally thanks to Patrick for introducing me to your work and opening my eyes to seeing perspective differently – I’m not sure I’m ever going to get over that... :-)
