I noticed that Germans built their houses with small bricks of various colours in the past. The colours created various patterns. You can often see brick houses with usually horizontal, vertical and oblique brick lines - perpendicular one to each other. The color bricks were often replaced by wood creating brick - nogged - timber - walls called "Prussian wall". You can see it either in Berlin/Germany and in parts of Poland which belonged to Germany in the past including my hometown.
Sometimes, especially on churches or other "more important" buildings the brick patterns were more complicated like on the round wall of the apse of St. Mathew Church (St. Matth?us Kirche). Enjoy :-)
