One that I like is called "Reel Streets" and what it does is take a shot from a film and does a then and now photo shot.

For someone like myself who has spent over 30 years riding around London and seeing the changes that had happened with the streets and buildings in London that time and to how they looked back in the 40's, 50's etc and seeing a build that I remember that's long gone to having a pint in the Jackdaw pub in Denton, Kent where Christopher Plummer and Susannah York in the Battle of Britain.
