I had really wanted to make it so that a user of my HTML5 Fractal software can specify an iterating function using familiar notation. This new version 2.0 makes that wish a reality. At the moment, there are limited functions that can be used in the iterating function, such as sin, cos, conj, and abs. Furthermore, exponents must be whole numbers (no fractions or imaginary exponents). I plan to overcome these limitations in a future version.

In order to draw a fractal using a custom iterating function, simply change the fractal selection to "Custom" and the interface to input the iterating function will appear. Try modifying the functions for the built-in fractals.

Unfortunately, this new version breaks compatibility with the hash URL syntax of the old version, but these are growing pains.
This software is growing in new directions and I have a vision of creating a tool that will serve two purposes.

- Fractals are useful in an educational setting, although they are generally considered "pure math".
- Some artists and designers use fractals for inspiration.
