       rocks - animation of flying through an asteroid field

       rocks  [-display  host:display.screen]  [-foreground  color] [-background color] [-window]
       [-root] [-mono] [-ncolors n] [-install] [-visual visual] [-count integer]  [-delay  usecs]
       [-speed integer] [-norotate] [-nomove] [-3d]

       The  rocks  program  draws  an animation of an asteroid field moving past the observer (or
       vice versa).  Sometimes the observer picks up spin on Z axis.

       rocks accepts the following options:

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

       -root   Draw on the root window.

       -mono   Make all the rocks the same color.

       -ncolors colors
	       How many different colors to use.  Default 5.  Colors are chosen randomly.

	       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
	       Maximum number of rocks to draw on the screen at once.  Default 100.

       -speed integer
	       A measure of the speed with which the observer and the rocks pass each other, from
	       1 to 100.  Default 100, meaning ``very fast.''  If you're on a slow  display  con-
	       nection	(the  animation  looks jerky) then try making this number smaller, and/or
	       decreasing the number of rocks.

       -delay microseconds
	       Number of microseconds to delay between each frame.  Default 50000, meaning  about
	       1/20th second.  Compare and contrast with -speed, above.

	       Don't rotate the observer; just fly through the field on the level.

       -nomove Don't turn the observer; just fly straight ahead through the field.

       -3d     Do  red/blue  3d separations: if you look at the screen with 3d glasses, the rocks
	       will be jumping right out at you.  Oooooh, scaaary!

       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.

       X(1), xscreensaver(1)

       There should be an option to display doppler shift (a gravity rainbow.)

       Speed of rotation should be settable.

       Default speed of rotation should be relative to forward velocity.
