absolutely possible. This was a couple of hours first try. I think I could
optimize the number of colors; right now it could go quite low. It will
take some experimentation. -- or finding the GIMP code where this is done
and just reproducing it.
background yellow;
set spinfps 5;
capture "caption-bh" spin x
See http://chemapps.stolaf.edu/jmol/test for some examples.
Let's keep comparing and refining.
