Kdron is both a remarkably simple and complex structure. Its basic has a square base, 11 multifaceted sides and a diamondshaped face with a 45° angle of inclination. Viewed from above, it is a square within a square. The surface structure is both symmetrical and asymmetrical, concave and convex. Kdron possesses exceptional optical properties. Several Kdrons placed next to each other create a dynamic number of possible patterns. Because of the opposite but complementary nature of its structure, two basic Kdrons placed on top of each other form a cube. Interaction with its form reveals the fascinating versatility of the Kdron and its potential product application. Kdron was patented in 1987, and a corporation has been formed exclusively to promote and market this new shape. The Kdron's symmetrical, concave and convex surface structure possesses dynamic optical properties. A group of Kdrons can be placed on a square grid in many different arrangements to create various surface patterns. These surfaces interact dramatically with light and shadow. When the angle of light changes, entire new groups of visual patterns are created. The visual effects resulting from arrangement and illumination are further expanded by changing the point of observation. Kdron's optical properties are inherently complemented with acoustical (including sound diffusing) values for both outside and inside constructions. Kdron allows the composition of an astonishing number of twodimensional surface patterns. A cube combined from one black and one white Kdron displays five basic patterns. This forms a base for the creation of infinite possibilities by simply increasing the number of Kdrons. Just eight (4 white and 4 black) Kdrons can generate 38.416 flat surface patterns.
