Hi all, I've decided to post ALL my code for my home made Christmas tree. It's simply the LED Strip (LPD8806) wrapped around a metal cone frame.
You can change programs (various ones from the Ladada examples, but also a number of my own - including the color phasing / interference posted on this forum yesterday, plus a great simplex noise based on happyinmotion's forum topic: http://forums.adafruit.com/viewtopic.php?f=47&t=24554).
You can also change 'patterns', i.e. the variations - usually color changes. This usually does different color combinations.

I'm not sure why GitHub rotated this image!
