Device for creating and displaying moire patterns

摘要

A device comprising a base plate having a first array of lines displayed on the upper surface thereof and at least one generally transparent upper plate member having at least a second array of lines marked thereon. The upper plate member(s) are juxtapositionable and rotationally movable over the base plate such that the arrays of lines present on the upper plate member(s) will interact with each other and/or the array of lines present on the base plate to create a variety of moire patterns. Some or all of the base plate and upper plate members may be premarked with desired linear arrays. Alternatively, some or all of the base plate and/or upper plate members may be provided in blank unmarked form to permit the user to draw his own linear arrays thereon so as to design the create unique moire patterns. A line drawing template may also be provided to assist the user in drawing the arrays of lines on the upper and/or base plates.
