Glass building brick with decorative surface - where decorative patterns of different shape blend together without frequent repetition of one design

摘要

The decoration consists of surface zones possessing different patterns which are not symmetrical w.r.t. at least one axis of the brick and all four connecting sides of the different zones are symmetrical w.r.t. the middle of each side. The connecting widths of the patterns on at least two opposite sides of the brick also possess the same length. The decoration is pref. completely unsymmetrical, and the bricks pref. have square surfaces visible to the human eye; and at least two bricks with different decorative patterns are pref. used together in an assembly of bricks, e.g. in a wall. An extremely large number of patterns can be created on large walls formed by the bricks without frequent repetition of the same pattern, so that extremely artistic effects can be created.
