I wrote a quick Mandelbrot set renderer in Clojure, after hearing the sad news that the great mathematician Benoit Mandelbrot passed away this weekend. Watch his TED talk (http://www.ted.com/talks/benoit_mandelbrot_fractals_the_art_of_roughness.htm...) and you will find it hard to feel as if you didn't know him. It was simple and fun to write, as Clojure has support for complex numbers. It took me a while to figure out how to turn that support on, though. It takes less than a minute to run, and can surely be optimized. http://github.com/vishsingh/mandelbrot The output of the program looks like this: http://github.com/vishsingh/mandelbrot/raw/master/result.png It can surely be extended quite easily to zoom in to smaller parts of the set.
