Although Shared Creation focuses extensively on Internet based creativity there is a certain rightness in looking at the real world too. LARP seems to bridge the both the digital and the real.
LARP is consenual group story telling - everyone agrees to a framework of behaviour and uses it to take part in the telling of a story. Its part a very modern idea, part a very ancient idea. The bridge between digital and realworld comes in the way that concepts, stories and characters are often developed online and then played out live.
Twilight Realms is a group that does this. The world is build largely online, and then enacted at events.
Very creative, very modern, and very retro.
