Analog Television Simulation Demo

James Halliday (Substack) is a fascinating developer. I was just looking at his github and noticed this recent project. Seems to be based on three code repositories:

https://github.com/substack/glsl-ntsc-video - modulate and demodulate an ntsc video signal in a shader

https://github.com/substack/ntsc-video-simulator - real-time ntsc television simulator

https://github.com/substack/analog-tv-simulation - the demo itself
