Are you drawing a comic and seeking inspiration for artwork? If so,
there's a lot of computer-generated biological imagery around the Web.
For example the "Home Page for Cellular Semiotics" at
http://new.math.uiuc.edu/cellular_semiotics/, which looks like an
attempt to script an intro (incomplete, unfortunately) to the immune
system. It's divided into several scenes, with birds-eye and close-up
views of immune system cells, and a commentary on what the viewer is
seeing as they zoom towards a cell.
You might also find inspiration in the Asimov book and the flim
"Fantastic Voyage", in which a (very) midget submarine gets injected
into a patient's bloodstream, and eventually has to evade the immune
system in order to escape being smashed to splinters by white blood
cells. One of the crew members was Raquel Welch. There are a few
images at http://www.foresight.org/Nanomedicine/Gallery/FanVoy/ and
its pages such as http://www.foresight.org/Nanomedicine/Gallery/Captions/Image196.html,
which shows the sub surrounded by red blood cells.
Oh, and 1980's issue of the journal "Trends in Biochemical Sciences"
(available in any good science library) have a number of cartoons,
notably by the incomparable TAB, depicting various aspects of
immunology as well as DNA replication, cell-membrane construction and
other matters biochemical. Plenty of invading viruses and bacteria
there. I prefer the artwork to Far Side - it's more precise and feels
cleaner. Some of these cartoons were collected into a book called
"Sticky Ends", published in 1986 or so, but I can't find mention of it
on the Web.
Not quite an answer to your question, but might help.
