3blue1brown is great, e.g. his Fourier transform animation is super intuitive: https://youtube.com/watch?v=spUNpyF58BY

He has opensourced his animation engine "manim" used in his videos: https://github.com/3b1b/manim

Thank you for showing me that Fourier transform video. I've never understood how it worked because usually they just show the integral and call it good.
