"Since the Sept. 11, 2001, attacks, Steve Rosenbaum has become what might be the world's largest curator of photos and videos related to the site. Now, he's sharing the best of those with the public for free using a novel medium: an iPad app.\nRosenbaum has whittled down his collection of 22,000 images, taken from the day of the attacks until a few weeks ago, into 400. His 400 hours of video has also been boiled down to an hour. The ability to show both photos and video was one reason he chose to use an iPad app [iTunes link]. Another was that his ambition for the project defied the categorization of traditional book publishers. \"They'd say 'The photobook guy is down the hall,'\" Rosenbaum says. \"Then they'd say, 'We don't do ebooks.'\" \nRosenbaum, a New York-based documentary producer and CEO of Magnify.net, is making the app free for 11 days and then will charge $9.99. The pricing scheme reflects his wish to both put a value on the app and to make it available to the public.\"I wanted it to be expensive, like $49,\" says Rosenbaum, \"but if it priced it like that, no one was ever going to see it. I wanted it out there and free is the right price.\" \nAs the name of the app \u2014 \"The 9/11 Memorial: Past, Present and Future.\" \u2014 implies, its scope is pretty broad. It provides everything from details about the Twin Towers' construction in the 1960s to details about the day of the attack to information about the National 9/11 Museum's creation. Rosenbaum says the iPad app was designed so people could skip around to the parts they wanted to see. \"Most people who lived through it say they don\u2019t need to see those damn pics ever again,\" says Rosenbaum. \"But the further away you get from New York, the more people want to connect with it.\"\nOf course, Rosenbaum could have put the same materials on a website instead. When asked why he didn't take that route, he says he likes the way people experience media on the iPad: \"I guess I think of websites as something people access from desktop computers.\""^^<http://www.w3.org/2001/XMLSchema#string>
