The hop program generates real plane fractals as described in the September 1986 issue of Scientific American.


hopalong accepts the following options: -window Draw on a newly-created window. This is the default. -root Draw on the root window. -mono If on a color display, pretend we're on a monochrome display. -install Install a private colormap for the window. -visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. -ncolors integer How many colors should be used (if possible). Default 200. The colors used cycle through the hue, making N stops around the color wheel. -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.


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 the RESOURCE_MANAGER property.
