No theme really. It's just supposed to be random and funny. The most difficult part was re-modelling the LDraw parts to work with the rigging. The poly's on the parts may be accurate in dimensions but they are nasty for animating, so all the limbs had to be redone, but the originals where helpful. Had to make my own stormtrooper helmets too since the parts weren't available at the time.
