NAME

juggle - juggling man screen saver.  

SYNOPSIS

juggle [-display host:display.screen] [-root] [-window] [-mono] [-install|-noinstall] [-visual visual] [-window-id id] [-pattern pattern] [-tail number] [-real|-no-real] [-describe|-no-describe] [-balls|-no-balls] [-clubs|-no-clubs] [-torches|-no-torches] [-knives|-no-knives] [-rings|-no-rings] [-bballs|-no-bballs] [-count count] [-cycles cycles] [-delay delay] [-ncolors ncolors]  

DESCRIPTION

Draws a stick-man juggling various collections of objects.  

OPTIONS

-display host:display.screen
X11 display to use. Overrides DISPLAY environment variable.
-root
Draw on the root window.
-window
Draw on a newly-created X window. This is the default.
-mono
Draw in monochrome.
-install  |  -noinstall
Turn on/off installing colormap.
-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 id
Draw on an already existing X window.
-pattern dqpatterndq
Specify juggling pattern in annotated site-swap notation. In site-swap notation, the "height" of each throw is given. E.g., "3" is the height needed to juggle a 3-Cascade. Note that these sequences need to be chosen carefully, to avoid collisions.

Annotations indicate relative hand movements or tricks:

-Inside throw (default)
+Outside throw
=Cross Throw
&Cross Catch
xCross Throw and Catch
_Bounce
-pattern dq[pattern]dq
Specify juggling pattern in annotated Adam notation. Adam notation is a little harder to visualize. Each integer n represents a cyclic permutation of (0...n). The equivalent site-swap value is determined by calculating how many of the permutations it takes to get back to the identity. The largest number used is the same as the number of objects in the pattern. The advantage of Adam notation is that these sequences do not need to be chosen carefully, since all possible sequences are juggle-able. Annotations are the same as in site-swap notation.

For example, both of these describe a 3-Shower:

-pattern +5 1
-pattern [+3 1]

For further examples, see the portfolio list in the source code.

-tail number
Minimum Trail Length. 0 - 100. Default: 1. Objects may override this, for example flaming torches always leave a trail.
-real -no-real
Turn on/off real-time juggling. Deprecated. There should be no need to turn off real-time juggling, even on slow systems. Adjust speed using -count above.
-describe -no-describe
Turn on/off pattern descriptions.
-balls -no-balls
Turn on/off Balls.
-clubs -no-clubs
Turn on/off Clubs.
-torches -no-torches
Turn on/off Flaming Torches.
-knives -no-knives
Turn on/off Knives.
-rings -no-rings
Turn on/off Rings.
-bballs -no-bballs
Turn on/off Bowling Balls.
-count number
Speed. 50 - 1000. Default: 200. This determines the expected time interval between a throw and the next catch, in milliseconds.
-cycles number
Performance Length. 50 - 1000. Default: 1000. Setting this smaller will force the juggler to switch patterns (and objects) more often.
-delay delay
Additional delay between frames, in microseconds. Default: 10000. Deprecated. Adjust speed using -count.
-ncolors ncolors
Maximum number of colors to use. Default: 32.
 

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.
