MoMoLight

The MoMolight for notebook computers is based on the "Philips Ambilight" technology. The idea is to make the user's viewing experience more comfortable by using a directshow filter to calculate the average color on the top, left and right border of screen. Ok, I understood everything up to that point got lost after the explanation that it sends the calculation to a microcontroller that does PWM control of three separate banks of red, green and blue cold-cathodes. Can someone explain this idea to me like I'm a 4-year old kid please?HackADay (currently down) [via TechEBlog]
