NOTE: We've guessed that
you're not using a client that supports colored tables and have tried
to compensate. Low graphics mode looks much better on clients that
do... we recommend switching to Netscape 3.0 or Microsoft Internet
Explorer.

Refraction
the bending of light
|
Refracted light is
light that bends as it travels from one substance to another. |
The amount of refraction that occurs depends upon the density of the
substance and the angle at which the light is entering the substance.
Light refraction is also responsible for other unique effects, like
bending the rays of a setting sun to give it
an elliptical, "flattened-out" appearance.
