What's The Swirl?

This design is roughly three or four years old. I found the .jpg on my hard drive and I have no clue where the original is (Mom's house?) I should find it and get a better scan. I'm thinking about re-scanning all my designs soon so that I can make them available online to buy as prints on RedBubble or CafePress or something. As much as I'd like to make originals for everyone who asks me (mainly family members named Andrew), I think this may be a better alternative for my current... uh, somewhat busy schedule... if you can call baking and laying around with the Snarky Beagle 'busy.'
