--cycles integer

How long to run each batch.  Default 2500 pixels.

--count integer

How many pixels should be drawn before a color change.  Default 1000.

--jong integer
--no-jong integer

Whether to use the Jong format (default is to choose randomly.)

--sine integer
--no-sine integer

Whether to use the Sine format (default is to choose randomly.)

--fps

Display the current frame rate and CPU load.

Environment

DISPLAY
