ShiftBrite Electric Eye

My first arduino project is a 3x3 matrix of ShiftBrite LEDs and an ultrasonic rangefinder. It’s a proximity-triggered light show.

I'm really enjoying the ShiftBrite modules. There's a ton of potential with them and they're very easy to use.

Very cool. Does anyone else have experience with melding sensors and shiftbrites?

The evilmadscience panel http://evilmadscience.com/majors/150-panelkits does something similar to what I would like achieve.

Could a sensor be used to increase the color from light colors to warmer colors as someone comes close?
