Not from me, but from a fellow artist called Iván Egues. He made this really nice movie about a cube that folds and scales into a pretty slick building. Unfortunately, stickman only appears at the end, and he doesn’t move. He did do a walkcycle to have him walk around in it, but it didn’t make the final cut.
Doesn’t really matter, because the movie is pretty anyway.
and off course a link to his site (nice interior renderings there!)
