The sixth issue of VIEW Magazine is now available for free on Apple's Newsstand for iPad/iPhone. VIEW is an art photography magazine developed exclusively for the visual possibilities of the iPad. In the latest issue, Nate Larson and Marni Shindelman use publicly available embedded GPS information in Twitter updates to track the locations of user posts and take photographs to mark the location in the real world. Another interactive project in this issue is Chris Dorley Brown's project "Spot the Difference". Chris took a photo at the same location (and sometime of the same people) over the span of nine to thirteen years.
