Gotta love BG Micro -- purple LEDs! Actually they weren't as exciting as I thought they'd be, looks like a blue one with some red around the edges, but whatareyagonnado?

Big surprise was the green ones -- man are they bright! You could light your refrigerator with one if you didn't mind looking at green food all the time.
