Abstract

Catadioptric projection systems, devices and methods, including a lens, an illumination source and a reflector, arranged to pass light through a medium and focus the light onto a surface, with a vibration source disposed proximate the medium to impart frequencies on the medium to effect movement of the medium, which may be oscillations, patterns or other movements. The vibration source may be a transducer, audio speaker. The illumination source includes one or more illuminators that may be configured as one or more LEDs, and passes through the lens and provides illumination from one side of the lens, to direct the illumination of projected light through the medium and onto the reflector surface, where the light is reflected off of the mirror surface and back through the medium, through the lens, and focused onto a surface. The device is configured with control circuitry for operating the transducer and LEDs.
