This is 2 of my Robot Characters, fully rigged and simple face shapes. A ship interior environment and an exterior shot model.
I did some animation with all of this, rendered off a ton of shots but never quite finished it. It had vocal recordings for them all robot sounding and everything. Maybe one day I'll get back to it.
This was done with Cycles in 2.64 I believe. I have it set to CPU render because GPU is crashing on me in version 2.68a.
