Here's one of my own animations for a change, I just uploaded it. It started as an experiment in making boxes from solids in After Effects and went on from there.
This Machine Thinks_Goto80 from djwaterman on Vimeo.
The music (as attributed) was found at this place, and a handy box roll rigging lesson discovered over at the School of Motion, I don't think this video would've been possible without it.
