    NAME
         rocks - animation of flying through an asteroid field
    
    SYNOPSIS
         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]
    
    DESCRIPTION
         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.
    
    OPTIONS
         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
                 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  connection (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.
    
         -norotate
                 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!
    
    ENVIRONMENT
         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.
    
    SEE ALSO
         X(1), xscreensaver(1)
    
    BUGS
         There should be an option to display doppler shift (a  grav-
         ity rainbow.)
    
         Speed of rotation should be settable.
    
         Default speed of rotation  should  be  relative  to  forward
         velocity.
