I am pretty sure this question was asked many times, but I looked through search and found over 500+ pages with nothing I really wanted.

So any ideas how to make one of these, Radioshack only thank you.

I know this consists of 500+ leds, I don't need it that big, just a little strip that I could possible build and programm.
List of important parts please choose from Radioshack once again thank you-JOhn
