Why was the baby ant so confused?
Because all his uncles were ants.

3D projectorIn 1901, Claude Grivolas, one of Pathe's main shareholders in Paris, France, patented a projector for three-dimensional (stereoscopic) movies viewed wearing spectacles with one red and one blue lens (French patent No. 310,864). He received a British patent on 23 May 1901 (No. 10,695) For filming, he used a dual camera arrangement which photographed images alternately. He then created one composite master film with the left camera images alternated with the right camera image. His projector had a shutter with one red and one blue transparent sections, with opaque quadrants between them. Left-eye images were projected through the blue filter followed by right-eye images in red light. The movie appeared black and white when viewed using red/blue spectacles.*[Image: rotating shutter with red and blue quadrants alternately project left (L) and right (R) frames of movie film.] |
