About 25 years ago I read an interesting book (Denkspiele der Welt) about wooden cube puzzles. After copying existing puzzles by means of blueprints, I decided to 'invent' my own cube.
Unfortunately the original cube made of wood got lost after my parents moved to their new house a couple of years ago. That's why I created a digital version. Here is the result: http://webgl.orionhub.org:8000/index.html
The Blender model can be found here: http://webgl.orionhub.org:8000/scene
The cube is not perfectly symmetrical. Anyway I think it looks pretty cool. And of course I'm not quite sure whether this puzzle was not already invented by someone else Let me know if you have seen it before, thanks!
