DESCRIPTION

15       The goop program draws a simulation of bubbles in layers of overlapping
16       multicolored translucent fluid.
17

OPTIONS

19       goop accepts the following options:
20
21       --window
22               Draw on a newly-created window.  This is the default.
23
24       --root  Draw on the root window.
25
26       --window-id number
27               Draw on the specified window.
28
29       --mono  If on a color display, pretend we're on a monochrome display.
30
31       --install
32               Install a private colormap for the window.
33
34       --visual visual
35               Specify  which  visual  to use.  Legal values are the name of a
36               visual class, or the id number (decimal or hex) of  a  specific
37               visual.
38
39       --count integer
40               How many bubbles to draw per layer.  Default: random.
41
42       --planes integer
43               How  many  planes  to  draw.   Default: random, based on screen
44               depth.
45
46       --delay microseconds
47               How much of a delay should be introduced between steps  of  the
48               animation.  Default 12000, or about 0.012 seconds.
49
50       --transparent
51               If --layers is greater than 1, then each layer will be drawn in
52               one color, and when they overlap, the  colors  will  be  mixed.
53               This is the default.
54
55       --non-transparent
56               Turns off --transparent.
57
58       --additive
59               If  --transparent is specified, then this option means that the
60               colors will be mixed using an additive color model, as  if  the
61               blobs were projected light.  This is the default.
62
63       --subtractive
64               If  --transparent is specified, then this option means that the
65               colors will be mixed using a subtractive color model, as if the
66               blobs were translucent filters.
67
68       --xor   Draw with xor instead of the other color tricks.
69
70       --fps   Display the current frame rate and CPU load.
71

ENVIRONMENT

73       DISPLAY to get the default host and display number.
74
75       XENVIRONMENT
76               to  get  the  name of a resource file that overrides the global
77               resources stored in the RESOURCE_MANAGER property.
78
79       XSCREENSAVER_WINDOW
80               The window ID to use with --root.
