I came across this book at work - as my boss often buys lots of books each month - our workplace looks like a library - in fact, I probably wouldn't have bought it myself, but saw it on one of the coffee tables during break and was curious how I could fractals to security and encryption problems.
No joke, the book is packed full of stuff, it's also very hands on. Great if you're interested in fractals but also if youwant to explore projects that do more - like fractal sound, procedural terrain etc.
