The Mandelbrot (https://en.wikipedia.org/wiki/Mandelbrot_set) (and related Julia (https://en.wikipedia.org/wiki/Julia_set)) fractals are organic, intricate, beautiful ... sometimes hauntingly so!

Here's a video exploring the fractal in immense detail:

This talk and demo will:

  • Explain the very simple mathematical algorithm used to create Mandelbrot and Julia fractals - including a very gentle introduction to complex numbers (they're not complex!) and seeing chaotic behaviour in action!
  • Live demo some of the images you can create yourself, using very simple Python code, and free tools you can experiment with yourself
  • Talk about how you might manipulate these images further to create even more striking images -, applying edge-detect filters, or adding an "oil paintings" texture to such images to great effect. Here's an example:

This talk is suitable for anyone who isn't an expert in coding or maths, it is intended to be an accessible introduction. Non-technical artists are most welcome!
