Here are my slides for my talk at the meeting of the Theoretical Chemistry section of the Danish Chemical Society.
Here are links to the sites and programs I discuss:
The cyclohexane Jmol example
ChemDoodle Web Components demo using Molgrabber
Molecular Workbench model of entropy (link to Molecular Workbench)
Avogadro model builder (see also this post on the autoopt tool)
Pen- and Screencasts
Wolfram-Alpha (see also this post)
Online homework using Peerwise (I recommend the last video on this page)
Update: check out the Molecule Calculator!
