Saturn's Hexagon

I found out today about a breathtakingly weird thing. Saturn, source of mystique to humanity, has a hexagon on its north pole. Now don't jump into silly conclusions about conspiracy theories of Saturn crop "hexagons" or Saturn beings drawing up their sign on the north pole to scare space nomads (us in 100 years) away, it is a result of a change in the velocity of an ongoing vortex that draws a persisting pattern of a hexagon. Think a Spirograph.
