For anyone who was in New York on September 11th, 2001, the memories are still uncomfortably vivid. If you weren't here, however, you might want to check out Ironic Sans' 9-11 Pictures in 3D. David Friedman created the images, and sent them along to us with a note: "you may have seen other 3D photos of Ground Zero before, but these are brand new, converted from a 2D Coast Guard helicopter video I found on CNN.com. Most of the images require those stylish red and blue glasses [bottom images above], but there are several image that can be viewed without them, by going cross-eyed [top set above]. Seeing the wreckage of Ground Zero in 3D is quite powerful, even for those of us who saw it in 3D already because we were there in person. "
