I have never heard of shadertoy, and had no idea what a shader was, until I watched this video made by the creator of the cool effect in the TFA: https://www.youtube.com/watch?v=u5HAYVHsasc
I want to upload a WebGL demo I've made but I don't understand where I input the vertex shader, only the fragment shader. The site lacks info on how it works.
That's the whole point of ShaderToy AFAIK: no geometry, all pixel magic. Whatever you see on there is entirely frag-shaders. If it looks like geometry, it's still just funky fancy formulas in image space

Very demoscene.
It's wonderful that many of these load in the blink of an eye and run silky smooth even on a 2 year old iPhone.
> // Interesting findings from original NES Super Mario Bros.:
> // -Clouds and brushes of all sizes are drawn using the same small sprite (32x24)
> // -Hills, clouds and bushes weren't placed manually. Every background object type is repeated after 768 pixels.
> // -Overworld (main theme) drum sound uses only the APU noise generator
Here's the author's video of the shader, for anyone on a device that doesn't display the shader or play the audio: https://www.youtube.com/watch?v=WrxZ4AZPdOQ
Anyone willing to share? :)
