It’s true i’m more artist than coder… But it’s not my first filter actually, the first one is here but not finished yet (and a bigger mess of a script). And yes i think i will make more filters, it’s a nice hobby and it prevents me from buying guitars 
Will have to look into github a bit though, never used it to be honest.
Thanks both! Nice to hear, especially when you know it was only a random one-liner to begin with.
I wonder what will come out of it?
Yes,and i don’t really understand what they do (and the shape0 variants?), except for shapeprevalent which you explained a previous post. In the end I’ll leave them in the list since they do some nice things with some images (chessboard for example).
