@simonschreibt You’re welcome! I’m glad you found it inspirational! 
If I have time to clean it up I might add it later!

You multiply either U with a scalar value, or V, or both (Tiling both will end up with a tiny texture in the corner though…). And if the texture is set to Clamp rather than Wrap in the texture import settings, when you tile it, there’s just going to be a lot of black space, if that’s the border color of your texture. And when you’ve done that, you have a gradient you can use to mask your distortion scale value!
I use the lerp to control how much I want the gradient to influence my Distortion Strength scalar parameter.
Now, like I said before, doing this in the V direction isn’t very good. Doesn’t work with Ribbons so I’m gonna re-work it. But that’s how I do it atm!
