It is scheduled to air on Public Broadcasting Stations July 6. My South Carolina station airs it at 22:00. I have yet to find out when the Georgia station will broadcast it. I've contacted the station to ask when it is scheduled for broadcast. (update July 2, see P.S.)
Two reviews: Islamic Art Blog and Muslim Oasis.
Here's some bonus footage off the PBS web site:
Watch Islamic Art: Mirror of the Invisible World (Bonus Footage) on PBS. See more from PBS Arts.
P.S.Georgia Public Broadcasting does not have a scheduled broadcasting date. Please consider contacting the station and Tweeting (message pre-configured) to inquire why it is not scheduled for broadcast.
P.P.S. (July 3) An employee of GPB talked to me by phone and told me GPB was not broadcasting the arts series. I spoke to the film's producer. He said that the Islamic Art film is part of a 7 night PBS arts series. PBS is providing all stations an 'evergreen' version of Mirror of the Invisible that does not mention the arts series. Thus, it can be shown independent of that series.
