Jeff Martin of 360cities has produced the largest indoor photograph ever: a 40-gigapixel, 360-degree image of the main hall of the 868-year-old Strahov monastery library in Prague, Czech Republic. Almost 3,000 images were shot over five days and then stitched together to make the mega-picture. You can take a tour of the picture, swing all the way around, and zoom in on interesting details.
