Windows 7 introduces an Adaptive Brightness service that requires an Ambient Light Sensor doodad to work. Is there software that turns a webcam into a (periodic) ALS that is compatible with the ambient brightness service?

There’s plenty on eBay for <$10, but most of them are for Apple laptops (though they can probably be adapted for general use). – Synetech Feb 10 '12 at 5:35

there is certainly some ways to achieve this using Autohotkey as is discussed here : Using a webcam as an ambient light sensor

But BackLight Unit coNTRoL should work :)
