Flash (working name Humidoro) is a command line application that boosts productivity.

It combines the Pomodoro technique—work broken into 25 minute intervals, separated by 5 minute breaks—with visual feedback from wireless lightbulbs made by Philips (Hue).

The lights are set to a more brilliant white for the 25 minute work period, flash to signal when 1/2 and 4/5 of the time has elapsed, and change to a relaxed orange during breaks.

Very much a work in progress, you can fork it on Git.
