If "Shake Box" is selected, then every now and +then, the box will be rotated, changing which direction is down (in order +to keep the settled balls in motion.) +.SH OPTIONS +.TP 8 +.B \-visual \fIvisual\fP +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. +.TP 8 +.B \-window +Draw on a newly-created window. This is the default. +.TP 8 +.B \-root +Draw on the root window. +.TP 8 +.B \-count \fInumber\fP +How many balls to display. Default: 300. +.TP 8 +.B \-size \fInumber\fP +Maximum size of each ball. Default: 25. +.TP 8 +.B \-gravity \fInumber\fP +Coefficient of gravity. Useful values are < 0.1. Default: 0.01. +.TP 8 +.B \-wind \fInumber\fP +Wind. Useful values are < 0.1. Default: 0.00. +.TP 8 +.B \-elasticity \fInumber\fP +Coefficient of elasticity. Useful values are 0.2 to 1.0. Default: 0.97. +Lower numbers make less bouncy balls. +.TP 8 +.B \-delay \fInumber\fP +Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.). +.TP 8 +.B \-nonrandom +Make all balls be the same size. +.TP 8 +.B \-no-nonrandom +Make the balls be random sizes. Default. +.TP 8 +.B \-shake | \-no-shake +Whether to shake the box if the system seems to have settled down. +"Shake" means "change the direction of Down." +.TP 8 +.B \-fps +Display the current frame rate and CPU load. +.SH ENVIRONMENT +.PP +.TP 8 +.B DISPLAY +to get the default host and display number. +.TP 8 +.B XENVIRONMENT +to get the name of a resource file that overrides the global resources +stored in the RESOURCE_MANAGER property. +.SH SEE ALSO +.BR X (1), +.BR xscreensaver (1) +.SH COPYRIGHT +Copyright \(co 2002 by Peter Birtles and Jamie Zawinski.
