DESCRIPTION

       There is a tentacled abomination in the sky.  From above you it devours.

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 int
               Delay between frames, in microseconds.  Default 30000.

       --speed ratio
               Less than 1 for slower, greater than 1 for faster.  Default 1.

       --count int
               How many tentacles.  Default 8.

       --thickness ratio
               Less than 1 for thinner tentacles, greater than 1 for thicker.  Default 1.

       --length ratio
               Length of the tentacles.  Default 9.

       --wiggliness ratio
               A  measure  of  how  bendy the tentacles are.  Smaller numbers result in smoother flexing; larger
               numbers make it "crinkly".  Default 0.35.

       --flexibility ratio
               Another measure of how bendy the tentacles are.  Smaller numbers result in straighter  tentacles;
               larger numbers result in more extreme curves.  Default 0.35.

       --color color

       --stripe-color color

       --sucker-color color
               The colors of the various parts of the tentacle.  Default green with a redish stripe.

       --slices int

       --segments int
               Larger numbers increase number of polygons in the object mesh.  Default 32.

       --no-smooth
               Make the tentacles appear faceted instead of smooth.

       --fps   Display the current frame rate, CPU load, and polygon count.

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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
