If you want books you can try these old books:

Dynamical Systems and Fractals (http://www.amazon.co.uk/Dynamical-Systems-Fractals-Computer-...)

Mathographics (http://www.amazon.co.uk/Mathographics-Robert-Dixon/dp/048626...)

Computers Pattern Chaos & Beauty (http://www.amazon.co.uk/Computers-Pattern-Beauty-Clifford-Pi...)

Fractals Images of Chaos (http://www.amazon.co.uk/Fractals-Images-Chaos-Penguin-Scienc...)

I suggest these because they all contain some kind of code.

I love this.

  Since I'm on an old book kick today, here's a link to an old book with similar, simpler, nice graphics.
