Coloured ThinkPad ThinkLight
DEFCON 1 lighting conditions for your home computer!
On ThinkPads and some other buisness series laptops, you used to get a little LED on top of the screen, so you could see what you where typing in the dark, now they just use backlit keys but whatever. You can just crack open the screen bezel and tape over the LED some lighting gels to give it a diffrent colour. It is a bit dimmer than normal with the gel over it, so might be worthwhile cutting a slighting bigger hole throuhgh the plastic bezel to get a good result.
