  • The Science Museum here in St. Paul has a musical stairway with sensors on the steps. They’ve put an LED / detector on one side of the step and a prismatic type reflector on the other side. Putting your foot down on the step breaks the light beam and plays the note. It’s nice and durable with no moving parts. It’s really nice that all the wiring is on one side of all the steps, and the other side is just reflectors.

No public wish lists :(
