We propose a system that reveals hidden physical properties of objects and the environment, and that reveals objects and aspects of the environment via their hidden physical properties. The display of these revealed properties should be coincident with their sources, both in space and in time. This coincidence serves to simplify the mapping of property to source, and to facilitate collaborative evaluation of these properties. The display should also be a simultaneous field rather than a sequentially revealed series of points, so that adjacent entities may be instantly compared. To demonstrate the strengths of such a system, we will build and evaluate a thermographic projector.
