Hi Jason,

I can't tell from your e-mail how much background you need on
fractals, so you might first want to look at this answer in our Dr.
Math archives for the basics and some good Web sites to visit.

There's also information to be found by searching the archives for the
word "fractal" (just the word, not the quotes).  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:

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.
