i'm going to buy an old juke box and outfit it with an arduino-controlled sensor such that it only plays a song if you bump it with your elbow like the fonz
@clive I mean actually though, this is how we operate the paper towel dispenser in the break room
It gets bored of letting people have paper towels when they wave their wet hands at it every so often, and will only accept a bump on the corner as a proper greeting
