    Can you describe the movements of the central icosahedron? (hint: they are quite specific, although in the end it may seem complicated) :)

    NOTE: the numbers aren't (at least consciously) part of that. They are tied to whether 196 is a so-called Lychrel number)

    (from a video animation i made for some game i am working on and a puzzle there)
