Hah, this idea has come to my mind a couple of times, since in the city that I live very near to, Rotterdam, there is a building with a "built in" light wall that can be completely controlled. It's normaly for promotional stuff etc. I wonder why no-one did this idea yet.
This is the building:

And this is what it looks like in the dark:

This was during a performace of Tiesto by the way

Another pic:

I guess doing something like this would be "a breeze" on this building since it was actualy meant to be a gigantic display anyway.....
I have no idea who to contact but I think I will drop the idea. Especialy since this building is owned by KPN, the biggest Dutch telecom operator, the idea of phoning in for a game should be something they will like

[Edit] It's 72x37 meters by the way.
This is/was an idea to project, not sure if this was ever done and if it can do it so smoothly....
