+The RGB Lamp was a little filler project.  A 4.2W CREE RGBW LED module is driven
+by a PIC16LF1933.  Learn more:

+A future implementation might accept audio input from a stereo jack or onboard
+microphone, use a DFT to examine the frequency components present in the audio
+stream, represent each of several bands of frequencies with a color whose
+brightness is proportional to the signal strength, then 'mix' the per-frequency
+color results into an RGBW output that can drive the LED module.  Because of the
+higher performance needed, we will probably use a STMicro STM32 or EnergyMicro
+EFM32 low power ARM Cortex-M3 processor.
