That's impressive; and for me a bit reminiscent. I got my doctorate staring at macromolecular structures through various attempts at presenting them in 3d. One of the earliest I encountered was called a "Richard's Box"[0]. That setup was a set of clear plastic sheets on which were plotted 'slices' of electron density which were subsequently stacked-up with suitable sized spacers and you looked down through the stack with an lamp beneath. This approach sounds very similar, but with an active display in place of each sheet of plotter output.
