Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered Shiftbrite LED ambilight setup takes things a step further by automatically adjusting the colour and intensity of the ambient lights on the back of the display to match whatever is on-screen. Plus, it's pretty easy on the eyes.
Don Howdeshell, of Don's Projects, details the entire setup, from start to finish, on his blog. He even provides the wiring diagram for his controller and the config file for his lights. If you have the time and are the DIY type, you could follow his instructions pretty easily from beginning to end. At the same time, it's a little advanced for a first Arduino-based project, so tread carefully if you want to try this out on your own. Still, all of the details are there and the results speak for themselves.
