The code works a treat once you get to grips with some of the keyboard commands.
If you want to explore fractals this is a good book to do it with. Highly recommended.
As an aside: I bought the kindle version. I saw the Panorama investigation into the appalling conditions Amazon staff are put under and I was shocked by it. At least buying the kindle version I haven't contributed to that stress since no physical item had to be picked. From now on I will keep voicing my concern at the way Amazon treat their staff through my reviews. Long live free speech!
Fantastic introduction to fractals with very clear explanations and examples. It's structured in a beautifully balanced way that provides you with ample understanding and some solid techniques to go off exploring yourself.
