USB Ambient Light
The dominant color of your monitor becomes the ambient color of the room
Plug in the USB cord and position the light bar behind your computer display.
A small program running in the background on your computer assesses the color of the pixels displayed and tells the USB powered light bar which colors to emit.
The program comes with some presets to change colors randomly,
hold one certain color, flash on the hour and show patterns known to energize, make calm or tired.
The light bar comes with small bendable legs, choice of diffusers and also is able to be temporarily affixed to the back of the display.
For brighter versions with more LEDs, an external power adaptor is included.
Programs available for Mac OS X, Windows XP/Vista and Linux. A widget allows easy control of the program with previews of patterns and colors in Mac OS X.
Coming to cheap international internet vendors near you.

||[+] I love USB gadgets (except for daft ones that fry your motherboard by warming your coffee...and the like).
||[+] but baked on modern TV's.
||Phillips has an alarm clock that does this
||They do have flat screen TVs that do something like this, but an alarm clock? Do you mean, it has an alarm clock that wakes you up by turning on a light? The poster talks about something rather different.
||This is a very feasible product idea. I wouldn't buy it, but I bet someone else would, and it has lots of applications for entertainment.
||Point me to the store, seriously.
It would make my time on the computer much less debilitating: I've got a desklight shining on the (dark coloured) wall right now which helps somewhat.
