2. The Doctor Who Fan Orchestra
http://www.youtube.com/watch?feature=player_embedded&v=fNBadCgPuBo The Doctor Who Fan Orchestra are an example of the power that a television show can hold. They're an online collective of musicians who perform Murray Gold's scores by recording their parts individually, and then sending them to each other to layer the song. Oh, and they're bloody fantastic. If that's not inspiring, I don't know what is.
