When Alice falls down the rabbit hole, she discovers a wonderful world of mathematics: Pascal's triangle, sequences of rabbit generations, and beautiful, never-ending fractals.

This is an interesting site for information on chaos and fractals. Includes links to interactive activities to learn more.

Making Mathematics provides a brief explanation and a list of examples of iterations.

This site provides some links to activities and lesson plans dealing with fractals and chaos.

A great resource for beginners. The site begins with a definition of iteration of functions, and proceeds from there to discuss fractal dimension.

Contains over five hundred Geometry articles, problems, puzzles, and games. Some sites relating to circles are provided within this list.

This page briefly illustrates and discusses fractals, which are closely linked to the concept of iteration (repitition.) Site links to well known pictured fractals.
