f.lux – Save your eyes!

A friend of mine introduced me to this program called, F.lux, pronounced Flux. It automatically detects your time zone, and adjusts screen gamma and brightness as day turns to night (and vice-versa). Thus, saving your eyes from the strain of a bright computer screen in the dark. It can be disabled from your icon tray if you need to do color sensitive work, and enabled again just as easily. This is a must have program if you’re a gamer, web surfer, student, programmer, or someone who stares at your computer for fun.
