Processing Tutorial: Creating Trippy Animations with the Superformula

The superformula is a mathematical formula created by Johan Gielis which can be used to draw lots of cool shapes. In this tutorial, we plot the superformula using the Processing programming language.
This video covers:
The difference between Cartesian and polar coordinates, and how to convert between the two;
How to transfer a mathematical formula into Processing code;
How to animate the superformula by changing parameters over time (this is the fun part!).
