In a previous post I wrote "The 3D version of ChemDoodle Web Components requires something called WebGL, which is not available in standard browsers yet, but should be soon. You can get access to it now by downloading Google Chrome (BETA)."
Now you just need Google Chrome or Firefox, i.e. if you view this post in the Google Chrome or Firefox 4 browser you should be able to interact with the molecule. Other browsers should include WebGL soon, and when it reaches Mobile Safari, it should work on the iPad.
This means ChemDoodle Web Components is ready for use in research and education. It's quite easy to use: see here for installation instructions and here for a simple html example. Furthermore, "Over the next couple years, we intend to match all functionality in JMol" according to Kevin Theisen.
I note that the ChemDoodle Web Components are open source, so feel free to pitch in!
