I just love the feel of this shader, it's not as complicated as some of the other nutty shaders you can find on ShaderToy, but it does a lot with a little and has such a nice chill vibe, especially with the music.
When I first saw it, I thought the raindrops must be pretty expensive, but the video shows how cheap they are to compute. There's a nice tiling trick so that the shader only evaluates one drop per pixel, but the tiling grid is moving so it's harder to see where the bounds are.
He's also using the Desmos math webapp to design some of the functions, which is a great reminder for me, I keep forgetting about it, and I need a good function plotter handy when I'm working on shaders.
