I've written a couple of articles on the subject:

• My fractals: how they are drawn and the math behind them
• Fractals in Higher Dimensions (and various related topics, with pictures)

Here are some other things you can read about fractals. (links last checked ??)

1. Godric's Fractal Gallery (A very nice illustrated introduction to what a fractal is.)
2. History of Fractals At the Univ. of Bordeaux, France. ( Mirror location.)
3. Chaos at Maryland (Univ. of Maryland, USA)
4. Fractal Curves and Dimension
5. How-to: Quaternions (Nice 3D drawing information.)
6. Sekino's Fractal Gallery (Need a bit of math for this but not too much.)
7. Smooth Escape Iteration Counts
8. Fractals made with n-body gravitational fields
9. A Fractal Lesson (Jr. High or High School level)
