        goop - squishy transparent oil and bubble screenhack


        goop  [-display  host:display.screen]  [-foreground color] [-background
        color] [-window] [-root] [-mono] [-install] [-visual  visual]  [-trans-
        parent]  [-non-transparent] [-additive] [-subtractive] [-xor] [-no-xor]


        The goop program draws a simulation of bubbles in layers of overlapping
        multicolored translucent fluid.


        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 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
        -count integer
                How many bubbles to draw per layer.  Default: random.
        -planes integer
                How  many  planes  to  draw.   Default: random, based on screen
        -delay microseconds
                How much of a delay should be introduced between steps  of  the
                animation.  Default 12000, or about 0.012 seconds.
                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.
                Turns off -transparent.
                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.
                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.


        DISPLAY to get the default host and display number.
                to  get  the  name of a resource file that overrides the global
                resources stored in the RESOURCE_MANAGER property.
