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 link to this video

Highly recommended video by Iquilez, in a similar vein: link to this video Watching the guy hack away at graphics is super enjoyable

On “Plotting hearts with Python and C”

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: link to this video
