Done fairly quickly, this is a crystal lamp I made for a friend. It is made from quartz crystal and plumbing fittings! The jade green color it glows was achieved with the use of an RGB LED with full voltage to the green diode and a little bit of voltage to the blue diode. It runs on a nine volt battery, has a nice little metal toggle switch, and the bottom screws open to reveal the battery inside! Done five months ago.
This is the beacon with power to the LED.

An AVR is Atmel's microchip competitor to the PIC. They're pretty inexpensive, and there's a lot of samples of them being used as RGB LED faders and color-shifters.

Obviously you'd either need to buy or make a programmer (not too hard), or you could find someone to pre-program some for you (I'd be happy to discuss this, or you could also ask around; I'm sure there's plenty of people who'll flash the program to chip for you).
