One of the more interesting entries into the Windows 7 “Code 7 Contest” is an application called “BackLight Unit coNTRoL (BLUntrl),” that turns an ordinary webcam as a Windows 7 Sensors API ALS data provider to control the BLUs of all attached monitors according to the ambient brightness. Easier for the eyes and the environment!. This conceptually simple but highly practical application lets you do on your desktop what newer model laptops also do – automatic backlight control, reports.
