Surfing through the net today and I found this post from Archinect about videos from AEC World Expo Online Conference. 21 videos (about 45 minutes each) from the various professionals. in their fields such as Wil Alsop, Alejandro Zaera Polo, Frank Gehry, Ben Van Berkel, Fred Dust and many others. Some of the videos are interviews and others are lectures given are different events. The theme for the videos is Technology and its role in areas of design.
