These presentations are placed here for individual, traditional classroom, and homeschool access. Largely photographic/visual, I have put images up in high enough quality for projection. The symmetry presentation, designed for the math-ed classroom, is intentionally standards-rich. The Grand Canyon presentation was designed for appeal to a broad audience of GCNP visitors, to include nonEnglish speakers (it is mostly visual with few words): the 42 slides that comprise the Canyon section address a fractal pattern in the walls and rim of Grand Canyon that was shown to me by ASU Geology Professor Paul Knauth. Dr. Knauth's 30-year interest in this pattern has nothing to do with its fractility. It is, however, a vivid and extraordinary example of fractals in nature.

Accessible in both PowerPoint and PDF, I belatedly learned that PC's and Mac's display some fonts differently, in particular, fonts that I have used. If you have a Mac, my advice is to download the PDF version, a viewer is free if you need one. A handful of links didn't preserve in the PDF version. To ensure that everyone has access to all of the links, I have made separate links documents (that aren't up at the moment because they need to be updated).

Keep in mind while viewing that this is a math-art website, I am not trying to instruct per se. These were put together with the input of experts who not only made suggestions, they helped out with content. Although the presentations are technically mine, in a bigger sense they are products of a collaboration of ideas and expertise. Some people who have helped want to stay in the background, but I am sure that Don Jones (Arizona State University), Paul Bourke (Swineburne University of Technology, Centre for Astrophysics and Supercomputing), and Reimund Albers (University of Bremen) will not mind being given credit as frequent sources of help and advice. I have referenced the Yale Fractal Geometry website many times and encourage people to visit their pages at http://classes.yale.edu/fractals/, as well as Cynthia Lanius' pages for those new to fractals at http://math.rice.edu/~lanius/frac/.
