Having grown up watching Aliens, I've been playing the knife game (or 5 finger fillet) since I was old enough to smear crap on walls (although I wasn't very good). Well now 5VOLTCORE has built a robot called the knife.hand.chop.bot that plays the game for you, you just supply the hand. The robot looks less than impressive, and goes pretty damn slow. I mean, with my finely tuned masturbatory skills I can pretty much do this at the speed of light.
A video of the robot playing about as fast as my grandmother after the jump. And then one of a kid who knows what's up.
