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.

       -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.
