Thomas Heatherwick is a designer who was behind the revisioned Routemaster bus, in use in London today, which was designed to be 40% more energy efficient.

In this TED Talk, Heatherwick takes us through a few other projects he has worked on, including the beautiful Seed Cathedral, where light comes into the building through thousands of optics. So much so that you can even see clouds, from the inside, as they pass by.
