I'm curious to see what people do with this design. Give it a different pose, create alternate weapons, cut it up and make an articulated figure out of it, etc. Play with the scale and make some prints (read How Big Can You 3D Print Your Stuff? to see how big you can make it at Shapeways) Please keep me informed on what you come up with!
