Shows interesting visual effects in tune with audio.

colorecho [-g] [-m]

Displays graphic patterns which are created by drawing a zoomed and rotated image of the screen back into the screen. This is similar to the effect achieved by pointing a television camera at a monitor showing the image from the camera: You see an image of the monitor on the monitor. The monitor image contains the same image and so on. This recursive feedback can generate fractal patterns in real time.

• -g Start without waiting for a button press.

• -m Never enter Auto mode.
