Rotational moire timepiece

Claim 1

A timepiece for producing moire images corresponding to the passage of time, comprising: (a) a plurality of plates arranged in generally planar layers; (b) each of said plurality of plates containing a pattern composed of a group of substantially optically clear areas and a group of substantially optically opaque areas, said patterns of said plurality of plates optically combining to produce multiple moire images; (c) rotational means for rotating said plurality of plates at clock speeds, whereby said moire image is constantly transforming; (d) at least two of said plurality of plates including different shaped time indicating means for communicating the time; and (e) wherein said patterns consist primarily of a series of angular linear shapes, said linear shapes having an alternating sequence of approximately 360°/N=Y and L+Y=X, where N is any integer for dividing said plate into a radial group of segments, Y is a rotation angle, L is any angle for said linear shapes for a selected segment from said radial group of segments, said linear shapes composed of substantially equidistant parallel lines and X is a rotated linear shape for a contiguous segment, said contiguous segment located counter-clockwise contiguously to said selected segment, said rotation angle Y being subsequently added to said rotated linear shape X and sequentially to all remaining contiguous counter-clockwise linear shapes of said radial group of segments, whereby the angular difference between each contiguous said linear shape of said radial group of segments is said rotation angle Y.
