I had a look and I am really struggling to understand the different mA capacity I will need etc. I was thinking of using these LEDs:
LED - RGB Clear Common Cathode - COM-00105 - SparkFun Electronics
Great as Sparkfun is, for 130 RGB LED's your better off (price wise) looking on ebay. You can get 200 of them here http://www.ebay.com/itm/200-pcs-5mm-4pin-Tri-Color-RGB-Common-Anode-Red-Green-Blue-LED-/120953667490?pt=US_Car_Lighting&hash=item1c29667fa2 for just under $40 where Sparkfun would cost just over $200 for 130 of them. It's worth getting extra on ebay as you can sometimes end up with mixed common anode/cathode or the occasional dead led.
