Vidding mostly involves making music videos of fan shows. Some are just illustrations of fan works, and some have themes or explore character. Some even change the stories or characters to new alternate forms, but I find some of the most interesting works are when someone uses video clips to tell a story that is new.
Exile Vilify by felixfelicius was one such story.
It told of John's sadness after the fall and how Sherlock was in town trying not to be seen while still watching over John.
Well, the second part recently came out , so I've posted it here.
Fandom is a form of communication and not simply imitation. Yes the elements come from the show, but the ideas and the actions are creating something new.
