DanceLight

DanceLight has six colorful modes:

1. Music + Tilt It
The color changes as you tilt the phone while the intensity changes with the music volume.
2. Color Organ A
The bass music makes the screen more red, the midrange frequencies make the screen more green, and the high pitched sounds make the screen more blue. All these happen at the same time.
3. Color Organ B
Same as Color Organ A except that the loudest range is always at maximum brightness. This makes the display much brighter, though you can't see as much change.
4. Music
The screen flashes white in time with the music.
5. Shake It
The screen color changes when you shake the phone. Up+Down is green, Left+Right is red, In+Out is blue. If there is no motion the screen is black.
6. Tilt It
The screen color changes as you tilt the phone. Flat on a table is blue, vertical is green, on it's side is red.

To change modes you simply swipe your finger across the screen.
