Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
91 words
A new art form comprising a backing sheet having a first precisely generated planar pattern imposed thereupon; a first transparent sheet having a second precisely generated planar pattern imposed thereupon, said second planar pattern being discernibly different from said first planar pattern and disposed in fixed relationship to said first planar pattern so that a viewer facing said transparent sheet from each of a plurality of vantage points observes a different one of a plurality of optical effects resulting from the visual coaction of said first pattern with said second pattern.
Claim 2
Dependent Claim
91 words
A new art form comprising a backing sheet having a first precisely generated planar pattern imposed thereupon; a first transparent sheet having a second precisely generated planar pattern imposed thereupon, said second planar pattern being discernibly different from said first planar pattern and disposed in fixed relationship to said first planar pattern so that a viewer facing said transparent sheet from each of a plurality of vantage points observes a different one of a plurality of optical effects resulting from the visual coaction of said first pattern with said second pattern.
