Don't have a clue about formula's. I'm probably one of the most illertate math people you're likely to have the misfortune of meeting :( However, I love the colours and the sihlouette type shape is making me think of 4 fluffly white swans mandala style with golden crowns on their heads. favourite desert snack? hmmm.... there are many (grin) one would be those little cheescake-in-a-cup things :)
