Abstract
Abstract An artistic-viewing device which, through the effects of internal opposed and angularly related mirrors, produces a variety of symmetrical optical illusions. The structure includes a three-dimensional housing having at least two pairs of opposing generally transparent walls, the interiors of said walls at portions thereof being covered by at least two sets of opposing spaced mirrors. The mirrors preferably are of elongate construction diagonally disposed with reference to the shapes of the sides of the housing and in opposing sets have their longitudinal centerlines disposed in crossed relation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
An artistic viewer for producing a variety of symmetrical and harmonious optical illusions having in combination, a three-dimensional housing having at least two pairs of spaced, opposing generally parallel sides constructed of sheet material through which light will pass, at least two pairs of opposed mirrors mounted respectively interiorly of said opposing sides and occupying less area than the total area of said sides thereby leaving light-transmissive generally triangular spaces between the marginal edges of said reflectors and the marginal edges of said respective sides, and at least one of said reflectors having a transparent viewing portion disposed medially thereof through which the interior of said housing, including said opposing mirror, may be viewed by a human eye.
Claim 2
Dependent Claim
118 words
An artistic viewer for producing a variety of symmetrical and harmonious optical illusions having in combination, a three-dimensional housing having at least two pairs of spaced, opposing generally parallel sides constructed of sheet material through which light will pass, at least two pairs of opposed mirrors mounted respectively interiorly of said opposing sides and occupying less area than the total area of said sides thereby leaving light-transmissive generally triangular spaces between the marginal edges of said reflectors and the marginal edges of said respective sides, and at least one of said reflectors having a transparent viewing portion disposed medially thereof through which the interior of said housing, including said opposing mirror, may be viewed by a human eye.
Claim 3
Dependent Claim
74 words
The structure and combination as defined in claim 1 further characterized by the sides of said housing being of generally rectangular configuration and said two sets of opposing sides having dark opaque framing at the peripheral edges thereof, said framing serving in the manifold reflections produced by said mirrors to combine in producing a great series of rectangular configurations with reflections based on the edges of said reflectors in a symmetrical overall optical illusion.
Claim 4
Dependent Claim
36 words
The structure and combination set forth in claim 1 further characterized by a plurality of adjacent walls of said housing, with the exception of the areas of said mirrors, being constituted of highly colored transparent material.
Claim 5
Dependent Claim
27 words
The structure set forth in claim 1 wherein the configuration of said walls is generally of polygonal shape and wherein said reflectors are generally of oval shape.
