The picture doesn't look like much. That's because the map isn't static.
That's right, it's a hack that shows you where someone has just ordered an item from Zappos. It's weird, and weirdly cool, and as my new BFF puts it "weirdly compelling."
Go to it (during the day, when people are actually buying) and let it sit there for a while and watch the commerce happen right before your eyes. I can't exactly articulate what it tells you -- certainly nothing you can say in words. But it gives you a perspective I haven't seen anywhere else ... something about the velocity of internet commerce ... or the quiet incidence of consumption ... or how people nearly pass like ships in the night, on an ocean of pixels and electrical impulses, their bodies far away from each other and all unaware of what they, in that instant, have in common.
