Cool Mod Idea

i was reading a guide on how to make a led visulation thing that uses a winamp plug in. It plugs in in a parallell port. It said there is other plugins and proggys for windows that can make the leds light up for other stuff. What i was wondering was if there is a plugin that will make the leds light up with cpu usage. I think that would be a cool mod. If i can find the page again i will post it so everyone can see exactly what i am talking about. Thanks!

It would suck for me, I have SOB running full-time =)
