I don't see one of these yet, so here's the question for the proposals for the October 2015 Community Challenge!

It's time to choose a for October 2015.

  • Post your challenge as an answer to this question. Feel free to resubmit non-winning ideas from previous months.
  • Vote for those answers which interest you.
  • At the end-of-day on Wednesday, September 30th, the top-voted post will become the next challenge.

Once the challenge topic is decided, post your solution as a question on the main site and tag it with . The challenge runs throughout October (but nothing stops you from posting an entry later on).

Mandelbrot Set Fractals

So it seems we started something here with Mandelbrot sets, so the proposal I want to make for October 2015 is to write a programme in your favourite language (or a new one if you're feeling adventurous) that will generate a Mandelbrot set fractal.

At the bare minimum it should be able to generate the entire Mandelbrot region from x: [-2.5, 1], y: [-1, 1].

Optionally it can support zooming and rendering custom regions.
