       rd-bomb - reaction/diffusion textures

       rd-bomb	[-display  host:display.screen] [-foreground color] [-background color] [-window]
       [-root] [-install] [-visual visual] [-width n] [-height n] [-reaction  n]  [-diffusion  n]
       [-size f] [-speed f] [-delay usecs]

       The  rd-bomb  program draws reaction/diffusion textures.  The code is derived from the 'd'
       mode of the "bomb" visual musical instrument (see  http://www.cs.cmu.edu/~spot/bomb.html).
       I got the equations from xmorphia (http://www.ccsf.caltech.edu/ismap/image.html), which is
       based on a version of the Gray-Scott model taken from:
	   John E. Pearson "Complex Patterns in a Simple System"
	   Science, 261,189, 9 July 1993.

       If the frame-rate is too low, consider decreasing the width and height  of  the	tile,  or
       decreasing the size of the active part of the screen.

       If one of the reaction, diffusion, radius, and palette options is set to a negative value,
       then that option will be set to a random appropriate value.

       Be sure to try "-speed 1 -size 0.1 -epoch 3000".

       rd-bomb accepts the following options:

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

	       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.

       -width n

       -height n
	       Specify the size of the tile, in pixels.

       -reaction n

       -diffusion n
	       These  are  constants in the equations that effect its visual nature.  Each may be
	       one of 0, 1, or 2.

       -radius n
	       Size of the seed.

       -palette n
	       Selects a palette.  Must be between 0 and 80, inclusive.

       -size f What fraction of the window is actively drawn, a floating point number  between	0
	       (exclusive) and 1 (inclusive).  Default is 0.66.

       -speed f
	       When  a	fraction  of  the screen is active, the active area moves at this rate (a
	       floating point number).	Default is zero.  Suggested value: 1.0.

       -delay usecs
	       How many microseconds to delay between frames; default 1000, or about 1/1000th  of
	       a second.

       DISPLAY to get the default host and display number.

	       to  get	the name of a resource file that overrides the global resources stored in
	       the RESOURCE_MANAGER property.
