pyro - simulate fireworks
pyro [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-count integer] [-frequency integer] [-scatter integer] [-fps]
The pyro program simulates fireworks, in a way similar to a Macintosh program of the same name.
pyro 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. -count integer How many particles should be allowed on the screen at once. Default 600. -frequency integer How often new missiles should launch. Default 30. -scatter integer How many particles should appear when a missile explodes. Default 100. The actual number used is between N and N+(N/2). -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.
