Rotational moire timepiece

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.degree./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.
