Feature list

See the page How to generate a colormixer about how to make that nice color mixer.

Feature	Comment	Priority	Version Impl	other
Select color from HSL/HSV	Behind the touchscreen, set a image (printed) with a HSL/HSV space and transform this to RGB according position. I just need the formula to draw a HSL/HSV space...	Med
Sensitive to sound	Add a mic and make the stuff sensitive to sound (easy : average volumne, hard : color according frequencies)	Low
Add modes accessible by buttons	Sine : around the selected color, make the brightness evolve slowly like a sine Random : like the MagicSango, from the start color, evolve randomly Flame : make the brightness evolve randomly while keeping the base color (little amplitude but quite fast to emulate a flame pulse) Stable : nothing (but you need it) 1 hour fade out : light will slowly turn off for 1h and the stop the whole arduino and led completely	Med/High
