Locate the searcher from the URL at the bottom of this message. Now - how are people using fractals? Probably one of the most well- known uses is for fractal image compression. Much of the information on the web is quite complex. Here's an article from American Scientist that's a pretty good place to start: http://www.sigmaxi.org/amsci/issues/Sciobs96/Sciobs96-09image.html An excerpt: Fractal Image Compression Mike May A little experience wandering the World Wide Web reveals that storing a digitized image, especially a high-resolution one, requires lots of memory. Viewing some homepages, for instance, is a painfully slow process even with a high-speed connection: While image files pour avalanches of bytes into your computer's memory, the page grows line by line on your monitor. Image storage and reconstruction may prove even more troublesome in the CD-ROM business, where someone might want to put thousands of images on a disk. Microsoft's Encarta CD-ROM encyclopedia, in fact, contains about 7,000 photographs. Getting them all on one disk required a technique called fractal image compression.
