The Heliodisplay is an air-based display that uses water condensed from the air already present in the operating environment. The system, developed by IO2 Technology in 2001, uses a projection unit focused onto multiple layers of air and micron-sized atomized particles in midair, resulting in a two-dimensional display with no visible projection surface. This is similar in principle to the cinematic technique of rear projection. As dark areas of the image may appear invisible, the image may be more realistic than on a projection screen, although it is not volumetric. The system may be viewed fr
