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.

There's an ancient book that is handy - 'Computers, Pattern, Chaos & Beauty'.

It has pseudo code and a bunch of illustrations. (http://www.amazon.com/Computers-Pattern-Beauty-Clifford-Pick...)
