Good primer. Reveals computer algorithms used. Have fun messing around with interactive animated white balls! The interactive chaotic pendulum engine near the end of the article is my favorite. Teaches you a'lot about chaotic systems. Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
