Abstract
Two plastic film transparencies are rotatably attached side-by-side by engagement of film portions on one transparency with at least one incision on the other. There are images on each transparency and the rotatable attachment allows relative rotation of the transparencies to overlay the images on the transparencies. The images are cooperative so that overlaid images provide cooperative images. The rotatable attachment is accomplished by film portions on one transparency engaging an incision or incisions on the other. In some embodiments of the subject invention at least one of the transparencies is essentially circular. In all embodiments of the invention the relative rotation of the transparencies is in a range of 10° to 360°.
Claims8
A display, comprising:
- a first plastic film transparency having at least one first image on it;
- a second plastic film transparency having at least one second image on it;
- said first and second transparencies being positioned side-by-side;
- said first transparency having at least three incisions in it;
- said second transparency including film portions that engage said at least three incisions in said first transparency to rotatably attach said transparencies to allow rotation one relative to the other in a range of 10° to 360° so that one transparency is rotatable relative to the other to overlay said images so that said first and second images provide a cooperative image.
A display, comprising:
- a first plastic film transparency having at least one first image on it;
- a second plastic film transparency having at least one second image on it;
- said first and second transparencies being positioned side-by-side;
- said first transparency having a circular row of circumferentially spaced apart incisions in it;
- said second transparency including film portions that project through the incisions in said first transparency to rotatably attach the transparencies to allow at least some rotation, one relative to the other so that one transparency is rotable in a range of 10° to 360° relative to the other to overlay the images so that the first and second images provide a cooperative image.
A display comprising:
- a first plastic film transparency having at least one first image on it;
- a second plastic film transparency having at least one second image on it;
- said first and second transparencies being positioned side-by-side;
- said first transparency having one incision in it, said one incision forming a circular hole;
- said second transparency including film portions that engage film material bordering said circular hole in said first transparency to rotatably attach said transparencies to allow 360° rotation one relative to the other so that one transparency is rotatable relative to the other to overlay said images so that said first and second images provide a cooperative image.
