Last February I blogged about Viktor Genel’s “ReCube” puzzle and the fun I had making cubical and spherical versions of it. Then, last August, I got to talking to George Bell about coordinate motion puzzles generally and about ReCube in particular. After some emails back and forth on how to model the spherical version in OpenSCAD, I realized I had omitted an internal vertex and the faces it anchors. I hate it when that happens. […]

Stewart Coffin’s “Burr Muda” Puzzle

I’ve been having a lot of fun with coordinate motion puzzles, some of which I’ve even blogged about. Well, one of the coolest is a Stewart Coffin design (STC-112) called “Burr Muda” and it looks like this: One of the things I really like about this design is that all six pieces are identical; that appeals to my sense of symmetry I suppose. Second, since it’s a coordinate motion puzzle, those six pieces must define […]
