Ancient Chinese algorithm to make 3x3 magic squares

There's a mechanical way to make any NXN square where N is odd. Start anywhere, writing numbers in sequence. Go to the upper-left each time, wrapping around horizontally and vertically.

When you get to the Nth, go down instead of to the upper-left.

That's it.
