Peter Greenaway is a mad genius of a director. His films make my head hurt, but I still like watching them. Via Jay is Games, I read about the Tulse Luper Journey:
It is being described as a “multiplayer” game, one that features 92 puzzles to solve and a community of players whose assistance you will need to seek for reconstructing the life of the mysterious lead character through pieces of a film.
I haven’t tried it yet, but I’m buttressing my brain as I write this.
