I have the DIY version [0] of this on the back of my monitor right now, and the effect is quite nice, especially when playing games. The total DIY cost was $30 in components, namely a Teensy 2.0 microcontroller and a WS2801 RGB pixel string from eBay (unfortunately, I don't have nice mounting hardware so they're just stuck in cardboard strips).
