Every now and then Johan Heyns posts an interesting picture
or three on FaceBook, something he’s experimenting with, something he’s made
for his own collection and sometimes it’s something he’s considering offering
for sale…
Sometimes those pictures find their way into the odd email
from Johan, with prices attached.
Sometimes I reply to those emails quite quickly and then
then send some PayPal in his direction…
Recently that rather rash behaviour resulted in the rapid
arrival of a pair of new co-ordinate motion puzzles … wooden sculptures that
come apart, really…
First is Tadao Muroi’s Triangle Explosion – assembled it
displays as a pair of triangles back to back – disassembled you have three
identical spikey pieces that look nothing like the assembled version!
Johan had removed the spikey ends on his improved design and
they will probably be a lot more puzzler-friendly and significantly reduce the
chances of dinging an end or unwittingly damaging a puzzler – I couldn’t stop
myself going for the thoroughly dangerous version!
…and going from disassembled to assembled is a wonderfully
tricky process requiring more than a bit of careful alignment. Johan’s bits all
line up beautifully and he’s taken the trouble to pin the bits together so that
they won’t be tempted to come apart with even the most enthusiastic puzzling.
Johan understands the importance of being able to properly
display his creations to really show off their features properly, so as with
his 4L Co-Mo DD, he’s included a stand that will allow you to display the
Triangle Explosion in mid-explode… where it looks great!
Next up was Johan’s own design for a Nest 4L(ayer) Co-Mo
which combines a pair of classic four-layer co-ordinate motion puzzles into a
single creation.
Pop the centre out and you have a pair of co-mo’s that slide
sweetly open and closed…Johan’s got the tolerances so sweet on these that when
you half open them and put them into their stand, they will literally close up
under their own weight…
Opening is simply a case of knowing when to do what and they
will slide apart beautifully…
Some lovely wooden examples of a classic mechanism – Dankie
Oom!
Have you tried the nested one simultaneously? Opening both while nested? Johan
