CHIME is an older, classic system for viewing protein structures from within a WEB browser (based on a separate, but related stand-alone program called Rasmol). CHIME requires a Netscape browser no later than 4.xx and CHIME must be installed as a browser plug-in.
For creating WEB presentation, Craig Martin has written CHIMEShell. Try it out. Though I'd like us to use JMolShell for presentations, if it's too buggy, we can revert to CHIMEShell.
