Tri-color LED Project: Mineral Light Show

My son has a piece of hambergite--I'm pretty sure that's what it is--and I've been wanting to give it special lighting for a while. Finally got a tri-color LED and wired up some switches so the colors can be turned on in combination. With this setup you can make 7 colors, red, green, blue, of course, and their complements, yellow, cyan, and magenta, and with all three, white. Hambergite is translucent with cleavage running straight along the length of it, so light travels through it well. So here are some pictures of the results.
