A visualization tool for atomic-level surface analysis.
I'm just getting started with AtoModel; I've only been working on it since 8-18-02, but I've got something useful already. You can check it out at http://www.sourceforge.net/projects/atomodel. So far, I've released the source code and the compiled binaries for Win32.
Well, I've got a lot to learn and a lot to do, so I can't write much more about it right now.
