This is an Iphone image from a recent walk/run program that I've been working at. I have a phone app that supposedly makes it easier to go from a couch potato to a 5K runner in a number of weeks (or months). I think I'm failing though, I doubt the developers had thought of all the degrees of inactivity the app would run across. The photo was shot at the local high school football field, the stadium wall had been coated with a textured surface that bubbled up. Passers-by peeled off the bubbles to reveal this ghostly image below.
