Some clips of a Peter Saville Q&A from the D&AD President's Lecture from March 12 can be found here.
Below is Saville talking about Banksy and his disdain of the British Gallery scene. I think this is the most interesting of the clips. Some of them just prove that designers are not necessarily more interesting than anybody else.
