       Draws a wobbling blob, making use of alpha blending, fog, textures, and
       lighting,  plus  a ``frames per second'' meter so that you can tell how
       fast your graphics card is... Requires OpenGL.


       -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

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

       -root   Draw on the root window.  -wire Render in wireframe instead  of

       -delay number
               Per-frame   delay,   in  microseconds.   Default:  10000  (0.01

       -fog | -no-fog
               Whether to enable fog.

       -walls | -no-walls
               Add walls for blob to hit.

       -colour | -no-colour
               Draw coloured blob.  If also textured, the  texture  will  have
               color mixed in.

       -texture | -no-texture
               Whether to wrap a texture image on the blob.

       -offset_texture | -no-offset_texture
               Whether  to ofset the texture calculations to only use a region
               of the image
                under the blob.  This works well with a semi-transparent blob.

       -blend | -no-blend
               Whether to draw a transparent blob.  (see  also  offset_texture

       -antialias | -no-antialias
               Whether to antialias lines.

       -resolution number
               Resolution  of  the tessellation used to calculate and draw the
               blob.  Larger
                numbers give a smoother blob but  increase  calculation  times

       -bumps number
               Number of bumps used to distort the blob.

       -hold-time number
               Time until loading a new image.

       -fade-time number
               Time taken to transition between images.

       -zoom number
               Size multiplier for blob.

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


       DISPLAY to get the default host and display number.

               to  get  the  name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.
