Some of the best do-it-yourself projects are ones that give you the functionality of an expensive commercial product on the cheap, and such is the case with RafkeP's MoMoLight "Movie Mood Light" mod, which lets you endow your laptop or PC monitor with the same type of peripheral lighting found in Philips' Ambilight displays. Unfortunately, also like many of the best DIY projects, this one requires no small amount of electronics knowledge and programming skills, as you have to modify your own micro-controller, procure and install your own cold-cathodes or LED strips, and then tweak the necessary software to get the effects synced with the on-screen action. Luckily RafkeP has taken at least some of the hard work upon himself and posted the directshow filter he wrote for real-time analysis of on-screen colors, making the build a lot easier once you've assembled all of the hardware components. It's still not gonna be a cakewalk to get everything functioning properly, but when you consider that a real Ambilight set costs several thousand dollars, being able to get similar results for under $90 is probably enough incentive to give this project a shot.
