NAME

       goop - squishy transparent oil and bubble screenhack

SYNOPSIS

       goop  [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-trans-
       parent] [-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.
