What is ISO?
Iso is short for ISOMETRIC
Isometric basically means that on all the axis,
there is one measurement.
Isometric was originally used in technical drawings, as it
is a quick way to make 3d(ish) technical drawings that are
to proper scale without the need of art. It is now used in
many computer games, like the Sims and Diablo. In the games
world, ISO usually uses tiles all in the diamond shape
making it easy to handle (see the tile writeup if you are confused)
Isometric images don't have perspective, so are quite easy
to draw (good for our cpus). They look a bit like this :

If you have a line spanning 20px, it must go up/down 10px
to fit in with the ISO look.
