Geo Magic Squares
Lee Sallows has written a book on Geo Magic Squares. I've not had a chance to peruse it. However, it is intriguing, though I do not claim to grasp the essence - yet!
On a side note: many people have written to inform me of Rubik's Cube iphone apps. Thanks. There are so many! I am interested in learning about the ones that offer something more novel.
