Claim 1
Independent Claim
211 words
An apparatus for obtaining continuously transforming projected images, comprising a projector with a light beams generating source of light and a screen surface at a distance from the projector, said projector directing said light beams according to its optical axis against said screen, at least one container of transparent material, said container containing a number of variously colored translucid movable substances, supporting means on said projector to support said container within the path of said light beams, said light beams passing through said container and the substances contained therein and projecting their images on said screen surface, means for agitating said movable substances, wherein, according to the improvement, said container has contained therein at least two non miscible translucid differently colored liquids and wherein said container has the shape of a flat box and said supporting means are in the form of a pocket adapted to receive said box shaped container, said pocket extending across the optical axis of the projector and wherein one of said liquids has a specific weight greater than the other of said liquids, and wherein said means for agitating the liquids is a pressurized fluid circuit including a pumping device, said pumping device injecting pressurized fluid into the container at the bottom zones of said container.
