Inigo Quilez builds a beating heart out of math, live-coding the shape and compositing it onto live video as he explains each step. It is an introduction to drawing with formulas in shaders.

HN people recommend it as a great beginner introduction and say watching him hack away at graphics is enjoyable.

His YouTube tutorial where he creates the beating heart composited on live video as he explains it is a great introduction for beginners and younger people [1]. I've learned so much from his sharing of his techniques and knowledge. Thanks Inigo! [1] ▶ this video

I was expecting it to be the same algorithm in two different languages, but the Python version is a mathematical description whereas the C version is RLE-compressed. Relatedly, there is this video on how to procedurally generate a 3D heart: ▶ this video
