I had a few hours to kill at the Sun User's Group meeting yesterday, so
I wandered around the vendor booths.  Imagine my surprise when I came
across a booth demonstrating chemical design software!  Here's a brief
rundown - this does not imply my endorsement of this product in any way.
I only had a few minutes to look at it.  Running on a SparcStation 1 it
seemed a little slow, and it was pretty clear that they were just going
through a canned demo, not actually doing any computation.  The "3D"
display was not true 3D, just depth-cued.  They had the choice of ball
and stick, skeleton, or dot-cloud representation (and more) for
atoms/bonds.  Balls were shaded.  The upper limit for graphics is about
1000 atoms per molecule.
