Abstract
A set of elements have square surfaces with patterns thereon, the elements being arrangeable such that the square surfaces are juxtaposed to form a design. The patterns are defined by one or two contour lines on the square surface, the surface areas on either side of each contour being different colors. The square surfaces have patterns belonging to two groups or have no pattern thereon. The first group includes square surfaces having only circular arcs as contour lines and the second group includes square surfaces having only straight lines as contour lines. The first group includes four types and the second group includes two types.

A combinable set of quadratic elements for laying out quadratic surfaces having variable appearance, with the sides of the surfaces being equal, said quadratic surfaces being divided into types of patterns with geometric dimensions equal to the half or the whole of the sides of each quadratic surface of different appearance, in which the number of quadratic elements is greater than the number of types comprising the following types where the quadratic surface is:
- (a) uniform in color;
- (b) divided into several non-overlapping and differently colored surfaces, with said colored surfaces adjoining along a 90-degree circular arc, the center of curvature of which lies in a corner and the radius of which equals half the length of the side of the quadratic surface;
- (c) divided into several non-overlapping and differently colored surfaces, adjoining along a 90-degree circular arc, the center of curvature of which lies in a corner and the radius of which equals the length of the side of the quadratic surface;
- (d) divided into three different colored surfaces, adjoining along respective 90-degree circular arcs, the center of curvature of the two arcs lying in a common corner, whereby the radii of the arcs respectively equal half the length and the length of the side of the quadratic surface;
- and
- (e) divided into several non-overlapping and differently colored surfaces, adjoining along a semicircle, the center of curvature of which lies at the midpoint of a side of the quadratic surface and the radius of which equals half the length of said side.
