f.lux your system and protect your eyes

If you are like me who like to work at the wee hours (just because sometimes you just get those cranky workarounds and logic just about that time ;) ) you may have noticed that the screen brightness of your laptop is too bright and painful. f.lux is a freeware application which when installed adjusts your monitor brightness and colour warmth according to the current time of the system.
