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] [-addi-
       tive] [-subtractive] [-xor] [-no-xor]

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: ran-
               dom.

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

       -delay microseconds
               How  much  of a delay should be introduced between
               steps of the animation.  Default 100000, or  about
               1/10th second.

       -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 addi-
               tive  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.

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_MAN-
               AGER property.
