Blending art and technology, 110 Stories enables you to use your iPhone to rediscover lost viewpoints and share memories about the 30 years the Twin Towers stood in Lower Manhattan. A radar display instructs you to point your iPhone at the site of the former Twin Towers, then uses augmented reality to render in the towers’ profile in a pencil-like drawing. You then take a composite photo with the towers accurately depicted in size, orientation, and location. Finally, you are asked to comment on what the photo means to you. Completed stories are submitted to a repository and map located on the 110 Stories web site.
