Elsewhen: a window through time. Take a photo of any place and drag a slider from a million years ago to a million years ahead. Elsewhen repaints that exact view in eleven eras, all from the same camera: a mammoth floodplain, the first huts, 1526, 1926, today, a garden city in 3026, ruins in a forest 10,000 years on. Buildings rise and crumble as you scrub, and each era has its own sound. Tap any spot to see it through every era, with a line on why it changed. Or switch history to see what your street would look like if Rome never fell.
