That's something entirely different from what I've posted, should have watched the video first.
You should look for sites about propeller clocks and the likes, it's based on the same principle.
There is a site with a RGB project much like this one at http://home.versatel.nl/edithenwilliam/william/magic.htm
It is based around a PIC16F628
but the site is in dutch, maybe you can translate it to a more suitable language with babelfish.
A video of the project over there running at http://home.versatel.nl/edithenwilliam/william/magic/mb_rgb.wmv
