                                 ANAGLYPHS

   Anaglyphs are a method of tricking the brain into thinking it sees a
3-dimensional view instead of a 2-dimensional view.  Normal "binocular"
vision presents two distinct images to the brain - a left eye image, and
a right eye image.  While nearly identical, the images are just different
enough to provide the sense of depth - the third dimension (Experiment:
Hold your index finger up in front of you, and stare at the wall past your
finger.  Now, close first one eye, then the other.  Notice how the finger
blocks a different part of the wall depending on which eye is open?  This
is the basis for 3D vision).
   Anaglyphs trick the brain by providing a "left-eye" image and a "right-
eye" image in one scene.  One image is drawn in red, then the other is
laid on top in blue (or green, or cyan).  The anaglyph red/blue glasses
"filter" out the "wrong-eye" image, so that one eye sees only the red image,
and the other sees only the blue image.  These two images, when drawn
properly, duplicate what a person would see if the scene were in fact really
3 dimensional, and, voila!  TRUE 3-D!
   In this program, the red lense should be worn over the left eye (or the
scene will look terribly contorted and inverted!).  There are six different
options for anaglyph viewing, as follows:
     1: Anaglyph Off - For those of you w/o red/blue glasses (you don't
                       know what you're missing!)
     2: Color 1      - Red image is grayscaled, Green/Blue is shades of
                       green and blue - Adds color, but has shadows.
     3: Color 2      - As #2, but red image is only red, no green/blue
                       grayscale component - prettiest, but shadowy, and
                       blue and red look more psychedelic.
     4: Red/Green    - dim, but not too shadowy.
     5: Red/Blue     - Most dim, but NO shadows at all
     6: Red/Cyan     - Brightest, some shadows, no colors

NOTE:  The anaglyph display mode can be changed AT ANY TIME by pressing the
number key (1-6) corresponding to the above list.
