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]  

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.
 

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.
