The Big O is a sign with deep historical and cultural roots, part of our heritage. It didn't deserve the neglect it suffered in recent times. It's lived under many names: the hash, the crunch, the hex (that's in Singapore), the flash, the grid. In some circles it's called tic-tactoe, in others pig-pen. From a distance it looks like the sharp sign on a musical score. Whether you call it a pound sign or a number sign or anything else, it retains its identity. It's so majestically simple that it always looks good, even if drawn by someone utterly without graphic talent. Good old #. It can't go wrong. nationalpost.
