Grant Sanderson of 3Blue1Brown shows his workflow for animating math videos with Manim, with Ben Sparks. He codes scenes live, including a Lorenz attractor, and walks through example scenes.

The old announcement trailer for Hyperbolica, CodeParade's Unity game set in hyperbolic and spherical space. The creator has since posted devlog videos on building it.

Sam Aaron live codes an ambient electronic set using Sonic Pi, the music programming environment he created. The performance shows code driving music in real time.

A long live-coded DJ set in which Sam Aaron creates all the music in real time by writing code in his Sonic Pi system. It demonstrates algorithmic electronic music performance.

John Lin reveals a rewritten voxel engine demonstrated in a Crystal Islands scene, with much finer voxel detail, fast collision, fracture and path-traced global illumination.
