Here are three talks I found thought-provoking and inspiring. All three demand some attention (and probably some time after to ponder what was said), but all three are also new ideas from thinkers who are breaking new ground. Very worldchanging.
Futureproofing the City: ZEDfactory; Foster + Partners; R/E/D from The Architecture Foundation on Vimeo.
Dan Hill-Keynote: New Soft City from Interaction Design Association on Vimeo.
Dan Barber on a remarkable food project: the sort of food shed every city should have.
(and, of course, you might find these talks I gave in November interesting as well.)
