goop(6)			      XScreenSaver manual		       goop(6)

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.
