Here is the video of my Functional Conf 2017 talk Haskell SpriteKit — a Purely Functional API for a Stateful Animation System and Physics Engine. In this talk, I am explaining how to wrap an OOish game engine API based on a mutable scene graph into a purely functional API based on an immutable algebraic data type.

This is the video of my Compose :: Melbourne keynote. I am making the case for purely functional graphics programming with Haskell playgrounds, including live programming a little game (for the second half of the talk).

Some of the code is hard to read in the video; you may like to refer to the slides.
