interesting, I think the shadertoy is in private state? website says it can't find the page

It's a python app using the MediaPipe framework to detect hand. Then the data is sent via OSC in Godot to interact with a particle system. You can learn about MediaPipe at ai.google.dev/edge/mediapi...

if you add "source_color" to the textures it's should be closer to the image, and also you may want to add the result and using the albedo

or use the "normal" and "light" variables, in the light pass

To blend between textures you could use the "attenuation" variable, which has the shadow value (but not only)
