Hey Atilla,
That would be cool! If you got 1000 people to sign up and chip in, it wouldn't be too bad. Then whenever a new person came out, they could chip in too, and we could build the network of billboards. Soon, we'd have billboards in every major city in America!
Hey, wait: I've got a great idea. How about we do some Greenpeace-style demonstrations. Like, project a giant "billboard" onto the side of the 124 Columbia Heights building at night! I wonder if there are any laws about that....Of course, that never stops Greenpeace....
