Zap... I was going to use this Idea for my case but i can't seem to get it to work correctly. so I am offering it to you. My Case has a nice size matrix of holes on the side to allow air flow. My thought was to take about 20 super bright LEDS and wire each one to it's own "randomly Pulsing PWM Circuit" Giving the effect of some type of radioactive material inside my case powering the computer. I was going to mount it somehow to a wheel to keep the circuit moving around in the case. and have the LEDS mounted on the wheel in a totally random fashion. I ask that if you can figure out how to do this let me know because i can't nail it down. This might be a neat effect for in the 2nd box. "!!CORE SAMPLES!!" Also you should get 2 or 3 of those green lazer pointers that you can see the lines coming out of it and make it look like the green is spilling out of the computer.
