Amit (Sudden motion sensor / Mac OS X Internals book) has some code and article on controlling the lighting on a Macbook pro – Im sure we’ll see some type of music aware disco mod soon….

Initiating an LED fade to a target brightness value over a specified duration. Retrieving and setting a display’s brightness.” [via] – Link.
