Sorry, I did not miss the obvious, I just forgot to mention it.

Consider the possible advantage of this approach:
ALL DIGITAL (I.E. Pulse Width/Frequency) color modulation.
No messy DACs or analog amps needed.

While we're on the subject, would someone out there in LED manufacturing land
please hurry up and make a simple color pixel consisting of RGB LEDs in one
diffuse package?  I could find quite a few uses for such a device! :-)
An imbedded controller would be nice, but I can wait for that.
