Convert Shadertoy into TouchDesigner and further integration

How to convert shaders from Shadertoy to TouchDesigner and integrate it with new environment with all CHOPs, TOPs and UI. This tutorial require basic GLSL knowledge only, I'll share some tips&tricks how to modified a code without full understanding of its meaning.
Since I closed this project, all Patreon only files are available now on github.com/exs...
And here is some helpful links related to topic:

I totally forgot to talk about licensing aspects of using shaders. By default, Shadertoy uses Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License, but authors can choose other options and mention it in the code or in the description. Please, pay attention to it, especially if you're going to use shaders in commercial works.
Also, I found a small mistake: at 1:34:40 I reference "Number of worms" from custom parameter in shader, but color TOP, circle SOP and direction CHOPs still referenced to params CHOP - that';s not good. You should either pass info from component to params CHOP and reference from it in other operators, or delete params CHOP and use parameters from the component in all places.

This looks complicated but I'm interested in checking this software out.

the call to radians() should be done inside main()
