Al Antaakii 15x15 concentric magic square, improved

For a long time I have been looking on in amazement at the Al Antaakii magic square, a 15x15 concentric magic square with all odd numbers within a diamond (and the even numbers outside the diamond). Later on I discovered, that it is easy to puzzle out this magic square using EXCEL.

But Jos Luyendijk shows us on his website that you can get a better diamond. In the diamond of Jos you find an (impure) 8x8 magic square.
