iSpan – augmented reality iPhone device allows you to peer through time giving the user a perspective on the scope of geologic time. When you hold the phone up, you see a split image of the current landscape juxtaposed with one from past or future. The camera’s “zoom” controls where you see in the future, e.g. +10 years forward or -1000 years back. The further into time you go, the greater the loss of resolution(color to grayscale, etc..). This device was inspired by Maya Lin’s Map of Memory and the Mannahatta Project.
