Live coding an Escher painting using Scenic

In this talk we will be rebuilding "Square Limit," a famous painting by M.C. Escher using Elixir, Scenic and the amazing powers of functional programming. We will build the whole application from scratch, and we will start by taking a look at how Scenic works. We will then proceed to decompose the fractal nature of Escher's painting and we will rebuild it step by step. By the end of talk, you should have acquired a good level of understanding on how Scenic works and a lot of respect for Escher's work as a mathematician.


Introduce people to the Scenic framework and stimulate their curiosity towards functional programming and fractals.


People interested in Elixir, Scenic, Escher and fractals.
