Magic Squares

A Magic Square is a "square" of numbers that add up the same vertically, horizontally and diagonally.
This is from Gaudi's Church of the Sacred Family in Barcelona, Spain. (It adds up to 33)
(I've been to this church and if you're every in this neck of the European woods it's a must see.)
This is a terrific Magic Square site.
