cloudlife - a cellular automaton based on Conway's Life


cloudlife [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-ncolors integer] [-cycle-delay microseconds] [-cycle-colors integer][-cell-size integer] [-initial-density integer] [-max-age integer] [-fps]


The cloudlife program draws a cellular automaton based on Conway's Life, except that cells have a maximum age, and only one pixel per cell is drawn every tick.


cloudlife 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. -cycle-delay integer Time in microseconds to sleep between ticks. Default 25000. -cycle-colors integer How many ticks should elapse between cycling colors. 0 to disable color cycling. Default 2. -ncolors integer How many colors should be used (if possible). Default 64. The colors are chosen randomly. -cell-size integer Size of each cell, in powers of 2. Default 3 (8-pixel cells). -initial-density integer Percentage of cells that are alive at start and when the field is repopulated. Default 30. -max-age integer Maximum age for a cell. Default 64. -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.
