               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
               The maximum height in pixels of each square. Default is 150.

       -max-linewidth integer

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

               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.
