This is currently a basic JavaScript-based fractal renderer. It requires Canvas support. The code is structured in a way that new it should be easy to add support for different types of fractals. Work items: -Improve performance(there are some easy optimizations available on Wikipedia(http://en.wikipedia.org/wiki/Mandelbrot_set#Optimizations) -Stop current rendering when a click event occurs -Currently, every pixel is drawn to the canvas separately. Drawing actually takes a significant amount of time(in seconds). Drawing continuous regions of color in a single operation could improve performance -See if HTML5 Worker Threads can be put to use
