Rock Band guitar mod turns on the magic of invisible light

Is the Rock Band strum bar too ... tangible for you? YouTube user adderd019 swapped out all that tiresome plastic in his Rock Band guitar for a beam of infrared light, turning it into an optical theremin of sorts.

The way he explains it, it sounds simple -- merely add an LED emitter and a receiver to the space where the strum bar usually goes, and then wire the controller up so that it registers a strum whenever the light beam is broken. Anyone can do that, right? The result is a guitar that strums when you wave your hand through the strum bar area. See the video after the break and marvel at the less-clicky, vaguely magical guitar!
