look for "arabesque" designs. 8 pointed stars, tesselated is a common one, as is the "moroccan lantern" look that's popular in tiles right now (that pattern started in persia, which is now iran.).

Hello Sir, For an apartment building, mold shall not be much of an issue. If it is done properly and the gaps are closed then even insects/cockroaches are not a problem in the brick walls. In fact they become more beautiful after some weathering and exposure. The man-made alternatives to actual brick finish are, brick tiles, brick wall papers, brick design laminates and MDF sheet. They are a close replica but personally we prefer actual bricks for the exteriors. Thanks, Nitin Cornerstone Designs Bangalore
