I got the source code right after comparing it with the one from the site at

Basically, this demonstrates the for statement in lots fo style. The authors went a little overboard with this one, because things such as Mandelbrot Sets are for persons who are VERY verse in math, and so to be honest i only have a very limited understanding of how this function is capable of achieving such a  complex pattern.
In full colours, this is what it looks like:-

and this is what the program printout looks like:

It's inverted and has pattern differences but as Wikipedia states, this pattern best demonstrates "Visual Mathematics".
Also, i found out recently that lots of math is in store for me in later chapters.

Very kool man!  don't worry u will grasp all the concepts! it just a matter of time...
u a gwan good thou giz
Yea, I'm supposed to make a interactive version of this program soon O_O
but, it shouldn't be THAT difficult, only a few variables that were assigned fixed values will prompt for the user to enter values within a certain range (this is where the ^ operator comes in for my version of the program Samath >.>) and then print a portion of the mandelbrot based on the integer range entered.

This should be out as soon as I'm finished revising chapter 5 @.@
