This is a fun little applet I whipped up one bored week. It generates random functions
f:[-1,1]x[-1,1] => [-1,1] and plots them within some color space. The results can be rather impressive.
The evaluation method is highly optimized and I intend to revisit it in the future for further improvement.
I recently added the Save button. If there are problems, questions, or suggestions, let me know.
