body: Basically the title, I want to create a tool that makes what I think are derivative works (word clouds made of other peoples words).
  
  
  If I wasn't selling the works could I profit off ads next to them?
  
  
  Or alternatively, since I technically only created the tool that makes them, not the works themselves, could I sell the word clouds?
