Key Lime Pi

This may be my favoritest ever Pi Day T-shirt, designed by the admin over at 10-Minute Math. I admit it’s not very mathy, but I’ve always enjoyed word play, and I love key lime.

The design won a Reflection T-shirt Company contest and is now available to pre-order for only $8.99 (plus shipping). [Company seems to have gone out of business? Can’t find their website…]

Unfortunately, it won’t be available in time for this Friday’s class.
