Ah, I see. No, actually it's some node stuff from the file sharing section. As far as I remember, it's called "1m cracks". As I said, I'm not at home atm, so I don't remember, who made it.
It's an intimidating pile of nodes, and I have absolutely no clue how it works, but it looks cool, and at the end there is a transform shader where you can adjust the overall size.
I used it for foam patterns for example.
