JSmol is the extension of the Java-based molecular visualization
applet Jmol (jmol.sourceforge.net) as an HTML5 JavaScript-only
web app. It can be used in conjunction with the Java applet to
provide an alternative to Java when the platform does not support
that (iPhone/iPad) or does not support applets (Android). Used in
conjunction with the Jmol JavaScript Object
(http://wiki.jmol.org/index.php/Jmol_Javascript_Object ), JSmol
seamlessly offers alternatives to Java on these non-Applet platforms.

JSmol can read all the files that Jmol reads. You can do all the
scripting that Jmol does. You can create all the buttons and links
and such that you are used to creating for Jmol. All of the rendering
capability of the Jmol applet is there. JSmol has both a console and
a popup menu.

JSmol is integrated fully with JSME and JSpecView.

A "lite" version of JSmol provides minimal functionality
(balls and sticks only) for extremely small-bandwith apps.
