The oldest work I'm aware of that uses this approach for producing fractals (clouds in this case) is Gardner's[1], from 1985. I dunno if Gardner's earlier paper from 1979, "Computer-generated texturing to model real-world features", contains the idea already because I could never find a digital version of that one.
