I just got this LED Lightpack - It is ambient backlight for your monitor ....and it just Awesome!!! it changes the colour of the light in the background behind your monitor when you watch movies or play games....the only thing is that it only works with a computer ....it very easy to set up... just sick the led strip to the back of the monitor and a usb to the computer.

here a link to video of what i mean ...
