A big thanks to Andrew Gale for getting a missing RGB  tree to me in time for Christmas. To celebrate (and avoid the wrapping),  I’ve cobbled together a quick Python App that gently runs through the spectrum on each of the LEDs in a random order. You can down load it from my git hub here (The colours look a lot better in real life).

Now the next question do I get on with wrapping or see if I can get it working with an Arduino …..
