Cardboard robotic arm

This was a pretty neat Kickstarter that ran over the summer, at the end of the day it's about a $200 computer controlled robotic arm made of cardboard.  The usefulness is somewhat limited, but the materials and relatively low cost ($200 for a 4 axis control board and 3 stepper motors is pretty decent) would make it a fun electronics project for learning with children.  Best part is that you could turn them loose with it when they are done, I don't see them killing themselves with cardboard.
