A three-dimensional display system for co-spatial point display of information emanating from at least two biophysical sources. The system includes a rigid, transparent three-dimensional structure within which is provided co-spatial visual display elements arranged in a three-dimensional geometry at regular coordinate addresses. Information input terminals, including terminals for biological interface, are provided. Also furnished is logic for assigning a three-dimensional coordinate address, at uniform time intervals, for the informational input from each of the biological sources. Each of the display elements are energized in a fashion that is input-responsive to the coordinate addresses corresponding to the system inputs. The system is further provided with detectors for alerting the users to spatial and temporal coincidence of energized visual elements resultant from simultaneous inputting of like coordinate addresses by the biophysical source.
