My whole life I’ve obsessively drawn spirals. I always thought it was some Celtic thing—a design surfacing from the collective unconscious. After a while I started adding little pointy flourishes to the curved lines-just for variety’s sake.

But after discovering the whorl shark, I wonder if beyond my obvious roots in the wet, gloomy world of the Celts, lies a more ancient connection to these tooth-wheeled prehistoric weirdos….

I hope so.
