@Dragonbot Sorry for the late reply, Steam failed me. Download this workshop item and take a look inside, it's just a script inside HTML. I actually grabbed this off someone else's conversion on the GLSL Sandbox, and it's buried by now. I know next to nothing about GLSL personally, so...
Feel free to modify and reupload this, I don't really care. If it's better, I'll remove this one.
There's also some unnecessary mouse-related code there, I'm actually glad it didn't work haha.
Even the original author commented that they could have done better.

well without having to attempt to reconvert it myself.

frac *= (sin(frag.y/iResolution.y*700.0)*0.5+0.5)*(1.0-distanceFrac); return mix(vec3(0.43, 0.77, 0.85), color, frac);
Swapping the 700 to 0 makes it a lot smoother is there anyway i could implement that to this?
