I just discovered this website and mobile app this morning. It appears as though this company is doing something I've long hoped for. I've always thought it would be amazing to see a historical visual record of a specific place. What this site endeavors to do is create a vast archive of historical imagery tied to specific locations. Ultimately, they hope to host a version of Google Street View that can travel back in time. Allowing users the opportunity to investigate a particular street in 1980 or 1880, etc. I like this idea a lot. I just downloaded the mobile app and am going to start tinkering around. Happy app-ing!
