Nic's way of being an architect was not traditional. He was doing mostly films and that's why he was not accepted as an architect, but in my opinion making all this with the buildings in a film is even harder.He was trying to explain that drawings are a good way of communicating ideas and spaces, but it can be more effective if it's used animation techniques. He showed some clips made by his students and they were pretty good especially when you know that it has been made by a student. One of his students clip was "Robots of Brixton" and it showed futuristic Brixton.
I really liked this lecture because of the way it was done.
