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.
