I've written a couple of posts in the past about Revomazes ... I really enjoyed solving (most of) them and the buzz you get when you open one of the metal puzzles and see the beautifully machined core stays with you for a long time ... but you have to work pretty hard to solve them (even the simpler ones) so a lot of folks never get to see those mazes - and trying to explain what's happening inside there can be a bit of a mission...
Now one of the things that the folks on the Revomaze forum have been baying for for a while, has been a clear sleeve, so you can see the insides as you're going through the maze - for demonstration purposes after you've solved the puzzle, of course!
...after several years of promises, attempts and false starts by a number of earnest puzzlers, my fellow blogger and mate from the 'States has finally achieved the impossible - he has machined a clear acrylic Revomaze sleeve, and sold a couple to eager puzzlers wanting to show off their Revomazes... and they are simply stunning!
How clear are they? Well, here's a close-up showing the pin through the sleeve and the maze itself... I think they're clear enough!
Well Done Neil! (and Thanks!)
