Want to see the New York turn into a grid of many, many corporate logos of our many, many corporate establishments? Presenting: City Maps, an interactive specimen of digital cartography for computers and iPhones that hooks directly into Twitter, Facebook, Foursquare, etc., etc., and maps geo-specific tweets. Reminds you of Logorama, right? Because why would you simply stroll down 5th Avenue when you can stroll and read site-specific, live tweets about what’s on sale where and whatnot? Right? All it needs is a little pop-up to tell you what traffic light’s on above your head, and you’ll never have to look up from your phone again.
