I'd also been looking for multi-colored LED sequencing lights which still appear to be uncommon. I did come up empty on those. I also manfully resisted the temptation to buy the "Lightshow in a Box" that Sam's had which allows you to pulse 12 separate outlets worth of lights in time to music, either built-in or of your own choosing.
After all, we'd like to finish decorating the tree before Christmas. :)
