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. […]

I guess I’ll just go with the flow and call them “coordinate motion puzzles.” One of the most beautifully made puzzles I’ve ever come across, coordinate motion or otherwise, is the machined aluminum / joined wood / metal 3D […]
