NAME

       goop - squishy transparent oil and bubble screenhack

SYNOPSIS

       goop  [-display  host:display.screen]  [-foreground color] [-background
       color]  [-window]   [-root]   [-mono]   [-install]   [-visual   visual]
       [-transparent]  [-non-transparent]  [-additive]  [-subtractive]  [-xor]
       [-no-xor] [-fps]

DESCRIPTION

       The goop program draws a simulation of bubbles in layers of overlapping
       multicolored translucent fluid.

OPTIONS

       goop 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 bubbles to draw per layer.  Default: random.

       -planes integer
               How  many  planes  to  draw.   Default: random, based on screen
               depth.

       -delay microseconds
               How much of a delay should be introduced between steps  of  the
               animation.  Default 12000, or about 0.012 seconds.

       -transparent
               If  -layers is greater than 1, then each layer will be drawn in
               one color, and when they overlap, the  colors  will  be  mixed.
               This is the default.

       -non-transparent
               Turns off -transparent.

       -additive
               If  -transparent  is specified, then this option means that the
               colors will be mixed using an additive color model, as  if  the
               blobs were projected light.  This is the default.

       -subtractive
               If  -transparent  is specified, then this option means that the
               colors will be mixed using a subtractive color model, as if the
               blobs were translucent filters.

       -xor    Draw with xor instead of the other color tricks.

       -fps    Display the current frame rate and CPU load.

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.
