Every time I see an article about scientists using sound waves to map a 3d image of something - around a wall, or just in general - I think of these tapers and how there's numerous tapes of one concert from different angles. I know that the tapers were in one area, but could they be far enough apart to map out a 3d model of the concert? What if you also had a few 2d photos of the concert - could a program be written to put it all together - how realistic can you get it? You could have the rest "made up" to fill in the blanks.
