"A meshtag is a "drawable barcode" that you can create by drawing straight line segments at 6 different angles." I count only three angles. The entire grid can be constructed via a series of parallel lines extending infinintely: one horizontal, one diagonal left, one diagonal right. There aren't any other angles.
