Mechanical artist Nemo Gould makes sculptures out of recycled and found materials -- we've seen that before.

What we haven't seen before is recycled sculpture that's not only fantastically creepy and retro (think robots with teeth and mechanical evil pixies), but also animated. Gould's sculpture Little Big Man, shown above, features a smaller robot visible in its guts that appears to be driving it. See io9's post on Gould for a video of it in action from a recent show at the San Jose Museum of Art, and Gould's own site for photos of the rest of his menagerie.
