looking for sound activated light?

This light I'm looking for had a spinning T inside with leds along their length that would change with sound pressure, shinning on the screen covering the front of the light. One of the simplest lights I have seen. Schmatics would be very helpful.

That light used a few concepts:

1) persistence of vision; look up POV light and you'll find lots
2) Sound organ -- similarly, lots of projects, more sounds = more led.

I'm not going to reinvent the wheel here, you'll need to search.
