I just got an interesting Christmas card from my cousin, with a very strange front.
Hey Sconibulus, I heard you liked puzzles so I thought you might have fun with this, the shopkeep guy said something about making circles around the numbers to get a hidden message for your campus square?
I hope you're having a good Christmas, and don't eat all the cookies too quickly!
I don't think the bit about the cookies is relevant to the puzzle, it just came with a box of very tasty cookies, (that are sadly gone now) but it's been included for completeness.
