What’s the deal with those brick buildings that have some bricks sticking out halfway or recessed halfway? There will be some big brick wall (like the side of a Wal-Mart or something), and every 50 feet or so along the wall there’ll be a column of bricks sticking out in a ladder-like fashion (i.e., only every second or third one sticks out). And there always seems to be a corresponding column of recessed bricks near the column of protruding bricks.
(The only purpose I can think of for these things is to tempt passers-by to climb the wall.)
