Accidentally created an optical illusion. Watch it for a while, then pause it (scrolling a bit can do this on dwitter), and it will appear to continue to move.

u/BriSeven

another part of this that interests me is that it appears to have a kind of lighting effect that changes as it rotates, but as I built the cubes up in layers of alternating colors, the lighting effect comes accidentally from the way the layers move further and closer apart as the rotate.
u/pavel

this is a nice trick
