Really, if you make 1000 collages per minute, the probability of any one of them becoming wildly popular is much less than if you only created one collage. The value of a work of art is largely based on it being unique, and there's no way you can generate 1000 works of art with the same algorithm and get any of them to stand out as unique. It's like asking what happens if you print millions of copies of a book and one of them becomes wildly popular. It won't, because there will be a million other copies of the same book. Randomizing some elements of the book won't change that.
