It starts out as just a white space with a set of simple platforms, and players with certain skills (painting, art appreciation?) could gradually uncover the actual art under the white space.
I was thinking of how players rush about from place to place all the time. It would be nice if there was a place where players could spend a lot of time collaboratively, and have a chance to chat more and such. Uncovering what is under the white space with other players would be a nice way to spend some chat time.
