Zappos Maps Sales in Real-time
Zappos, the online shoe retailer, maps sales across the United States in real-time. We've seen this before in Twittervision and other Google Maps mashups, but the difference here is that every shoe that pops on the map is cash in the bank. Keep that in mind, and this mashup takes on whole new meaning. Disregard the bug that doesn't reposition markers on zoom.
