Robozoic, by Brett Doar, has a very simple brain created with a rotating cylinder which works similarly to a music box. Robots in ArtBots aren't always the art itself, for example, some robots participating draw or create music. One especially interesting artistic robot was MEART, a brain-cell/mechanical arm hybrid which creates abstract "portraits."
