Overview:
In order to keep the example browser-independant, many of the features
had to be removed, as well as slowing the timing so that IE can execute
the JS Code fast enough, and still be able to re-render the screen. (For
those who were unaware, NetScape executes JavaScript much faster than IE.)
In this example, you're presented with 9 fish (3 each of 3 separate species),
who will swim about the tank pseudo-randomly, at varying speeds (depending on
species), in and out of the swaying plants (by modifying the Z-Index),
all in front of a backdrop which was 'stretched-to-fit' via layers.
To do: Probably nothing; IE has enough trouble running it already.
