Above is a cartouche of my name, from King Tut's Treasures, Inc. Go there to see your own name in hieroglyphichs. The squiggly bands represent water.
A cartouche is an oval band circling a god or pharaoh's name (my secret is out). The band symbolizes continuity.
They were dubbed cartouche by French soldiers (I'm guessing Napoleon's) in Egypt who thought the ovals looked like gun cartridges.
