               How long to wait between drawing each screenful. Default is 1 seconds.

       -min-width integer
               The minimum width in pixels of each square. Default is 40.

       -min-height integer
               The minimum height in pixels of each square. Default is 40.

       -max-width integer
               The maximum width in pixels of each square. Default is 150.

       -max-height integer

       -max-linewidth integer
               The maximum width of the lines used to draw. Default is 25.

       -min-linewidth integer
               The minimum width of the lines used to draw. Default is 2.

       -erase

       -no-erase
               Whether  to  clear  the  screen  after  each  screenful  is drawn. Default is True

       -square

       -not-square
               Whether to force the tiles to be square. Default is True (square).

       -curves

       -no-curves

       -scroll-overlap
               The amount to scroll from one side to another. Default is 400.

       -anim-delay
               The time to pause between each animation step. Default is 100.

       -anim-step-size
               The amount of steps to skip between each animation step. Default is 3.

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
               to get the name of a resource file that overrides the global resources  stored  in
