At the Newseum last week, Allyson and I saw a short “4-D” movie on the history of journalism. We were given special glasses to wear, and the 3-D effect was impressive. As for the fourth dimension, we were told we were being taken back in time. But something must have been screwed up with the museum’s time-space continuum, because, when the movie ended, we’d actually been transported 18 minutes into the future. Go figure.
