Attempt at a port of "Sinking" by zguerrero on shadertoy https://www.shadertoy.com/view/MsVfWy

Instead of Shadertoys built-in noise channels I used some noise textures from Cables and animated them.

I also changed the color from blue to green-ish, but this is hidden deep in the fragment shader code.

There is a weird interaction with the size and aspect ratio: try making the window really small!
