Folding a rectangle

Shawn Cornally posted some neat wonderings in the context of thinking about abstraction. [url]http://shawncornally.com/wordpress/?p=3941[/url] "This question goes like this: If I take a rectangular napkin and fold it so that the diagonally opposite corners touch, what’s the area of the new modern-arty shape? Second, why do I like the shape? (but that may be for another time)"
