Here are a few of the books that I used to produce the images shown on these pages. There is also an abundance of online material (Wikipedia and Wolfram Mathworld are great resources) - this is just a starting point for those who may be interested in pursuing the subject.
The original coffee table Math. book. Technical articles, very readable essays, including a charming one from Dr. Mandelbrot. Beautiful pictures and a "Do It Yourself" section with skeleton computer code and parameters corresponding to the illustrations.
A continuation of the above with sections on additional topics such as Turtle Graphics.
String-rewriting systems (turtle graphics) - fascinating material with lots of programming opportunities.
The original classic. Heavy going at times, but bursting with ideas and pictures.
Source texts for icons and quilts - formulas, sample parameters and computer code.
A charming foray into the world of symmetry by a gifted author and professional mathematician. Technical material can be lightly skipped over.
More technical - lots of fun multisyllabic jargon
At noon, the well was half full.
That evening, it was three quarters full.
The following morning, it was seven eighths full.
By lunchtime, it was fifteen sixteenths full.
Come teatime, it was thirty one thirty seconds full.
At this rate, nobody knew where it would stop.Stephen Leacock (paraphrased)
