Well, you know when you have writer's block, builder's block, troller's block, or any other kind of lack of creativity, what do you do? I say this because many people do odd things to get inspiration.
Me? I strum on a foot-long American girl guitar until something comes to me. Started once when I had writer's block and banged on a piano... Then the guitar was there when I broke my piano and it was just so much more entertaining.
