How long to run each batch. Default 2500 pixels.
How many pixels should be drawn before a color change. Default 1000.
Whether to use the Jong format (default is to choose randomly.)
Whether to use the Sine format (default is to choose randomly.)
-fps Display the current frame rate and CPU load.
DISPLAY to get the default host and display number.
