Can't unwind without the aid of open spaces? Skippy the robot might be able to help you out. The aptly named bot lets you remotely skip stones across an Idaho pond using a simple web interface. After waiting for your turn in a virtual queue, the machine lets you adjust its aim, tweak the amount of force behind the pitch and dispatch a rock. Best of all, your stone jumping exploits are automatically recorded, letting you show off your skipping prowess. Devised as a way to raise awareness for Idaho's Sun Valley resort area during the summer months, the mechanical projectile chucker seems to be arduino-powered, and operates only during daytime hours. Check out the source to start pelting pebbles, or venture past the break for two short videos of the contraption in action.
