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  num-
                bers  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.
