Abstract:
1. A projector apparatus, comprising: a housing; a lens mounted within the housing; a light source mounted in the housing and operable to project light through the lens onto a projection surface; a first slide mounted in the housing between the light source and the lens, the first slide causing light from the light source to project a first defined image upon the projection surface; and a second slide mounted in the housing between the light source and the lens, the second slide causing light from the light source to project a second defined image upon the projection surface, the second defined image being less focused than the first defined image; a motion slide mounted in the housing between the light source and the lens, the motion slide including at least one motion element movable in response to a stimulus and introducing an interference in light cast by the light source onto the projection surface, the interference providing an appearance of movement of an image projected by the at least one second slide wherein the stimulus is provided as airflow causing the at least one motion element to move thereby creating the interference as the light interacts with a reflective surface of the at least one motion element.
