DESCRIPTION

The strange program draws strange attractors

OPTIONS

strange 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.
-ncolors integer: How many colors should be used (if possible). Default 100. The colors are chosen randomly.
-points integer: Change the number of points/iterations each frame. Default 5500. More than 6000 activates the accumulator, which makes parts of the image brighter or darker depending on how often the attractor hits each pixel.
-point-size integer: Changes the size of individual points. Default 1.
-zoom float: Zooms in or out. Default 0.9.
-brightness float: Adjusts the brightness for accumulator mode. Default 1.0.
-motion-blur float: Adds motion blur. Default 3.0, no motion blur is 1.0.
-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.
