If you're able to design virtual movie characters, as in Pixar movies for example, you can make them move in the real city, and that could be very nice!

You can also give a try to the Photo Tourism website, based on the same concept (Java is needed). It's easy to use, just select some area, and wait a few seconds until the photograph loads. Then you can either step back to see a larger view, or select another area (in the picture).
