A new version of TwistyMol is available. It's now ready for use by others (that means YOU). Here's a simple example and here's another with a few more molecules.
What's changed since last time? Well I've added in an SDF file parser, made it possible to have multiple TwistyMols on the same page, sorted out the rotation (at least for the moment) and gone a bit overboard on the shadows. Performance on IE is still a big problem, and displaying more than a handful of molecules at the same time is out of the question (too slow). I still don't know if this is an intrinsic problem with VML or just the whole Canvas to Excanvas to VML conversion.
Feel free to modify and distribute the code. You could add a comment below with a link if you use it anywhere.
