Yup. I have always found fractal image compression to be quite 
fascinating. I like the way it can turn a scene of nature into 
probability ranges and create IFS formulas that use them. The neat part 
is that decoding is just iterating these formulas, or codes, and 
plotting the results to the screen resulting in a fractal representation 
of the original image.
