This meetup will be in Cornwall, not London.

Probably the most famous fractals are the Mandelbrot and Julia sets. They are organic, intricate, and hauntingly beautiful!

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

The aim of this session is to understand how simple mathematics creates these infinitely-detailed forms.

We're very lucky to have Brod Ross, a local algorithmic artists, kick off the event with a 10 minute talk showcasing his exploration of 3D worlds created using the 'Mandelbulb' variants of the popular fractal.

Here's an example by another artist: https://goo.gl/vUyRFT

We'll take gentle steps:

* start from the idea of iteration and feedback with simple arithmetic

* learn about complex numbers (they're not complex!)

* see unexpected behaviour from very simple functions - including mathematical chaos!

* understand how the Mandelbrot and Julia fractals are just a map showing how numbers behave

* try a few creative ways of colouring and rendering these fractals

And for those more confident with maths:

* see a short proof of the escape condition that helps compute them quicker

* see them in a new perspective - the folding and rotating effect of complex operations

We'll share easy-to-read code that creates these fractals, and also take a brief look at tools you can use.

You don't need to be confident with mathematics to enjoy this session. Non-technical artists very welcome!

The aim is to ensure that everyone leaves with at least an intuition of how these patterns are created, and an inspiration to explore them yourselves.

----

For this session you don't need to bring a laptop.

We'll be starting at 6pm not 6.30pm. Parking is usually free in the council car parks at this time.
