Abstract
A device that creates visible light in space comprises of a light source and optics system that result in irradiated visible spectrum light rays with a low intensity such that the light is not visible by the normal observer. Multiple rays of visible-spectrum low-intensity non-visible light intersect. When the constructive intensity of the intersecting light is above the threshold for being visible then light appears at that place. The light rays to and from the visible light remain non-visible. The addition of irradiated visible light results in additional visual effects. The visible light can be moved in space, and form multi-dimensional images and holograms. User and programmable controls, with communication abilities and data storage, can mediate the light source and optics to control the visible image.
