     ways

SYNOPSIS
     distort [-root] [-window]  [-mono]  [-install]  [-noinstall]
     [-visual   visual]  [-window-id  window-id]  [-delay  usecs]
     [-radius  pixels]  [-speed  float]  [-number  int]  [-swamp]
     [-bounce]   [-reflect]   [-vortex]  [-magnify]  [-blackhole]
     [-slow] [-shm] [-no-shm]

DESCRIPTION
     The distort program lets circular zones of distortion wander
     randomly  around  its  window, apparently distorting what is
     under them due to the window's pseudo-transparency. The mode
     of  distortion and the overall behaviour of the zones can be
     influenced in various ways.

OPTIONS
     distort accepts the following options:

     -root   Draw on the root window.

     -window Draw on a newly-created window. This is the default.

     -mono   If on a color display, pretend we're on a monochrome
             display.

     -install
             Install a private colormap for the window.

     -noinstall
             Don't 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.

     -window-id window-id
             Specify which window id to use.

     -delay usecs
             Specify  the  delay  between  subsequent   animation
             frames in microseconds.

     -radius pixels
             Specify the radius of the distortion zone in pixels.

     -speed float
             Specify the speed of the distortion zone, where  1.0
             is  kind  of  slow,  0.5 is twice as slow and 2.0 is
             twice as fast.

     -number int
             Specify the number of distortion zones.

     -swamp  Instead of letting zones wander  around,  let  small
             zones  pop up like bubbles in a swamp and leave per-
             manent distortion.

     -bounce Let zones wander around and bounce  off  the  window
             border. This is the default.

     -reflect
             Mode of distortion that resembles  reflection  by  a
             cylindrical mirror.

     -vortex Whirlpool-shaped distortion. Way cool.

     -magnify
             This mode of  distortion  looks  like  a  magnifying
             glass.

     -blackhole
             Suck your pixels beyond the event horizon. Favourite
             mode of Dr Stephen Hawking.

     -slow   Make the zone wander slower.

     -shm    Use shared memory extension.

     -no-shm Don't use shared memory extension.

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.
