Ewen, this is much appreciated. All you have to do is fill out a feature 
request, and who knows? You may be done with Chime before you know it. 
So please take a moment and fill in one request per distinct feature at 
http://sourceforge.net/tracker/?group_id=23629&atid=379136

I had never heard of Chime's Sculpt mode, but if it's anything like 
Jmol's "draw" mode, where you can move arrows and axes and planes and 
such around in space -- but with atoms -- this is certainly a 
possibility. Right now using JavaScript you can move atoms; doing this 
with a mouse should not be a big deal.

I'd like to hear more about Scuplt mode. How does it work? (From the 
user's perspective.)

I think part of what you are seeing is a response to what is at 
http://en.wikipedia.org/wiki/MDL_Chime:

"Calculating and drawing molecular surfaces coloured according to 
electrostatic or hydrophobic potential. Chime can calculate these 
surfaces for any molecule."

This is a BIT of an exageration. Chime has no magical powers. When you 
give Chime a set of coordinates, this is in no way sufficient 
information to "calculate a molecular surface according to electrostatic 
potential." Although the Chime programmers are sworn to secrecy, I have 
come to the conclusion that whatever they do in this regard is a 
convenient fake. Something that looks OK, but isn't in any way 
"according to the electrostatic potiential" -- at least not any 
generally accepted potential. They are faking the charges on atoms, 
probably using simplistic electronegativity ideas. Egon and others in 
the Steinbeck group at CUBIC in Cologne, Germany, and I had an extensive 
discussion on this back in August, and we concluded that the proper 
quantum mechanical calculation of charges is beyond the scope of even 
Jmol. So our solution is to render any electrostatic potential for any 
molecule for which charge data are provided. This includes an 
ever-widening range of formats from a number of calculational programs. 
If anyone finds a file format with charge data that are not being read, 
all they have to do is ask, and the charges will be there the next time 
around.

As for lipophilic surfaces -- does anyone know how to calculate this? If 
it's simple, we can just plug it in to Jmol as another isosurface option.
