The Mandelbrot Set is a fractal image produced from a simple equation. The cool thing about the Mandelbrot shape is that its edge has an infinite length, this means that you will never find a part of the set that is straight. Due to this interesting property it is possible to zoom into the edge and explore the amazing world inside this fractal.
I have written about it in more detail on my main blog. Once I have turned it into a screensaver I will write about it more here.
For now here is a basic version of the source code that has just the controls in.
Arrow keys to navigate.
/ to half the iteration count.
* to double to iteration count.
- + to change the zoom factor.
