...across the square, I saw it: the world's largest Windows error message - on a two-story high e-billboard (I guess everything really is bigger in New York). It was the only billboard in the entire square with absolutely no movement - since the PC running it had obviously frozen.
If this were a framebuffer on a unix system, perhaps controlled via SDL, this sort of thing simply wouldn't occur. I can only imagine how much time on a jumbo video display costs to buy. I'm sure that a few hours of lost broadcast is worth far more than a linux box.
