cardboard box robot

for a recent computer graphics project, we had to make a stick figure that played some motion capture data (where someone does some actions wearing a bunch of position sensors). we could do various things for extra credit, so i made him into a cardboard box robot. he gets pushed around a lot. the purple boxes i just threw in there - he can walk through them.

the cardboard doesn't look very good - i was hoping for something more realistic. but something like below is probably out of reach for real time rendering, at least for a while.
