These two industrial grapplers don't just have cute names (one of them is called "Bender"). They've got a cute control method as well, as they can be jiggled, jaggled and, yes, waggled by a Wii Remote.
These guys used a control system written in Python to replace the arm's regular input (a joystick) with the Wii Remote's internal sensors. So you don't even need the IR pointer, they just respond to tilting.

Shame they didn't go one step further and invent a few little industrial moving arm games to go with it.
