  • Solar phosphene generator
    Patent number: 5382204
    Abstract: A phosphene generating toy can be operated either by the user's blowing in a tube or a solar powered motor. In either case a spinning shade oscillates sunlight on the closed eyelids of the user, thereby generating phosphenes. A mini-flute also produces sounds. Safety features to preclude accidental gazing directly into the sun with open eyes include child proof shutters and a spring loaded shutter.
