       mirrorblob - Draws a wobbly blob that distorts the image behind it.

       mirrorblob  [-display  host:display.screen]  [-visual visual] [-window]
       [-root] [-wire] [-delay number] [-fog]  [-walls]  [-colour]  [-texture]
       [-bgimage]  [-offset_texture]  [-blend]  [-antialias]  [-x_res  number]
       [-y_res number] [-field_points number] [-hold_frames number] [-fps]

       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 sec-

       -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.

       -bgimage | -no-bgimage
               Whether to also draw the texture on the background.

       -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 when blend is enabled.

       -blend | -no-blend
               Whether to enable blending. (see also offset_texture above)

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

       -x_res number
               Number of verticies around the middle row of the blob (see also

       -y_res number
               Number of rows of verticies used to calculatethe blob, combined
               with x_res to
                indirectly determine the number  of  triangles  used  to  draw
               blob.  Larger
                numbers  give  a  smoother blob but increase calculation times

       -field_points number
               Number of points used to distort the blob.

       -hold_frames number
               Number of frames between changing images.

       -fade_speed number
               Speed at which fading occurs when changing images.

       -fps | -no-fps
               Whether to show a frames-per-second display at  the  bottom  of
               the screen.

       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.
