I really wish I were the sort of person who collected links on creativity to share, but other than Csiksentmihalyi's idea of flow, I got nothin'.
If anyone's looking for a discussion topic, how about... hmm... how is the writer-artist collaboration going? Do you write (or read, if you're the artist) a scene and think that would look perfect illustrated? Do you somehow know exactly what song sets the perfect mood for the vid and captures the tone of the story? (Writer picks the song? Or vidder picks the song?) How's it all working out for everyone?
