Pictures: Ghostly photos mixing the City of old with new

Check out these images from the Museum of London which mesh old photos of the City with shots from today. It's spooky, it's interesting, we like it.
The images haven't just been created for a laugh.
The images have been created to publicise an update for the Streetmuseum app which allows you to overlay the view through your camera phone with a historic photograph of the area.
Forget Instagram, this is Histogram.
