goop - squishy transparent oil and bubble screenhack
goop [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-transparent] [-non-transparent] [-additive] [-subtractive] [-xor] [-no-xor] [-fps]
The goop program draws a simulation of bubbles in layers of overlapping multicolored translucent fluid.
goop accepts the following options:
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- 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 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.
- 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.
- Draw with xor instead of the other color tricks.
- Display the current frame rate and CPU load.
