Does anyone know 1. How to wire a color changing led in to a circuit. 2. Where he got that cool led enclosure?

You can get them from ebay. It's just an RGB led. Or in this case maybe just RG - they do make them too. To wire them up it's just the same as a normal LED except you have a common anode or cathode depending on the type you get. So what you do is with switches or uC you can turn each LED on or a combination of on.
