Overview
This draws a bunch of moving circles which switch from visibility to invisibility when they intersect.
Options
-
--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.
-
--window -
Draw on a newly-created window. This is the default.
-
--root -
Draw on the root window.
-
--window-id number -
Draw on the specified window.
-
--delay number -
Per-frame delay, in microseconds. Default: 5000 (0.01 seconds.).
-
--count number -
Number of circles. Default: 32.
-
--ncolors number -
Number of colors, only one of which is used at a time. Default: 256.
-
--colorspeed number -
How fast the color changes (0 - 100). Default: 10.
-
--minradius number -
Minimum circle radius (as a proportion of screen height). Default: 0.05.
-
--maxradius number -
Maximum circle radius (as a proportion of screen height). Default: 0.2.
-
--db | --no-db -
Whether to double buffer.
-
--fps -
Display the current frame rate and CPU load.
Environment
-
XENVIRONMENT -
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
-
XSCREENSAVER_WINDOW -
The window ID to use with --root.
