What more can I say? It would be like heat gradient display, except it would make a light wave, or a warped wave. This would make it look cool and be more realistic.
i WOULD love a display like this that would be the equivalent of the pressure version of a "topographic map"
perhaps either have the elements greyscale , like in the life display, or have the pressure "waves" greyscale and the elements just the same they are in the nothing display
