color changing text?

[MonkeyBrain]

I almost want to say glow but that is not essentially what this effect does. I have seen it on many pages and it takes regular text like what I have here, and (upon mouseover) it changes from one color to another, at whatever the set speed and brightness is.

Please respond if you know what I am talking about :)
Thank you

you can edit the color at the top of the page and the speed settings below color
