This is an exciting website, written by Dr Andrew Hudson-Smith, aimed at examining the latest techniques to visualise the city scape via digital media. How to make movies is explained at the tutorials page, I think I will have a closer look on this shortly, but for now I decided to go just for the fun-stuff: two great movies.
1. Just Breathe (with also very interesting Telepop music)
And 2: Growing Pains; The story of a tree outgrown by an evolving city.
