Islamic architecture in Google Video

Google video, a very useful tool that is quickly developping, has posted these last days a well done documentary on Islamic architecture. "Paradise Found: A documentary on Islamic architecture", made by the British "Channel 4", lasts 1h 33 min. The quality of the video is good. Unlike so many other documentaries this one seems to me relatively more successful in presenting accurate information with a good narrative accessible to the wide public.
