I recently had the pleasure of an email conversation with a magician from the UK (who is a friend of a friend), called Chris Wardle.
Chris has come up with a really novel application of the well-known Reversible Magic Square, which I first saw in Royal Vale Heath’s book, Mathemagic.
He calls his routine the Dual Magic Square, and when you read it, you’ll understand why.
To the best of my knowledge, this is an original creation that I’m sure many will find intriguing.
Anyway, it’s very ingenious and well worth a look, whether you’re a magician with an interest in magic squares, or a mathematical enthusiast.
