From another ListServ (I think), I heard about ChemSense animation software. I've been looking for a good, easy to use, cheap (preferably free) software to use to create animations of molecular movement/processes as a part of the ancilliary materials for my new textbook. I've looked at several, and this is by far the easiest and fastest to learn. You can see it and download it at www.chemsense.org and there's a 5 page "Quick Start" guide (PDF file) you can download that really does show you all you need to know to get you started. They also have examples made by teachers and students on their site, and activities designed that you could do with your students. I played with it this morning and made a movie in about an hour--I can see that my next one will go much faster as with anything, there is a learning curve!
