This article from BBC News discusses how two mathematicians made a crochet model of chaos. The mathematicians, whose research focuses on developing a computer model to describe complex surfaces, were able to represent the Lorenz equations using 25,511 crochet stitches. The pattern was published in the journal Mathematics Intelligencer and the mathematicians are challenging others to repeat the...

Paul Bourke of the Astrophysics and Supercomputing department at Swinburne University of Technology is the author of this massive resource on fractals and chaos. He gives examples of many different kinds and classes of fractals, including the Mandelbrot set and various attractors; and brief explanations accompany each one. A substantial introduction to fractals covers the underlying principles and...

Written by Glenn Elert, this online textbook is aimed at "anyone with an interest in chaos, fractals, non-linear dynamics, or mathematics in general." Although it is not extremely technical, the author recommends having a decent mathematical background. Many people will recognize, at least by name, some of the topics covered. Mandelbrot and Julia sets are two well known fractals, and the book...
