Important: the program described below runs under Mac OS 7 to 9 only. If you use another operating system (Windows, Mac OS X, Linux), please se my list of 3-D physics animations (Quicktime and AVI files).
All the programs below have been developed a few years ago, and run only on Macintosh computer with MacOS 7, 8 or 9. There is no Windows or MacOS X version. Each program is now offer at the special price of 5 USD if you order them through Paypal (orders made through Kagi are still at the original price between $15 and $20 per program). Before purchasing, please download the programs and make sure they fit your needs.
