Magic Square - TAM Dr. Wiseman presentation

[IllegalArgument]

If you were at TAM3 and saw Dr. Wiseman's presentation, the math trick he demostrated at the end is called the "Magic Square". People seemed to really enjoy how he presented it, so I thought I would post a link to a website describing it.
