I think that before we can judge on the utility on such a presentation, we need the right visualization tool. My hunch is that viewing this with an Oculus would be an entirely different experience.
That's a good point. One 2d screen doesn't seem to benefit from the 3 dimensions.
Having it all around, visible and linked might change everything. Very much like whiteboards or other 3 dimensional physical representations (think like in Cop TV shows) help us to see the big picture.
