A fog display, fog screen, vapor screen or vapor display is a system that uses haze machines or water vapor to create a semi-transparent wall, or "curtain" of suspended particles which trapped in a thin sheet (Laminar Flow) of air and are illuminated by a projector, in order to produce a display whose images seem to float in mid air. Several commercial systems exist, such as FogScreen, Displair and Heliodisplay. There is also an open-source variant being developed called Hoverlay II
