I've stumbled upon this bizzare, yet intriguing game: The Endless Forest.
It is a screensaver/game thing, where you play a male deer! No chat, no violence, but you communicate with other players by deer body language. You wander about in this, well...endless forest and random stuff happens. It's based loosely on Princess Mononoke...Very fun
