There is an interesting article in today's JP.

Stephen Gabriel Rosenberg does some textual analysis and comes up with an interesting idea.

His idea is that the "Shnei Luchot Habrit" normally translated as the "Two Tablets of the Law" is actually translated wrong. Actually it was one stone tablet with the law written on both sides.

I recommend reading this article, it has some interesting insights into other aspects of the "Luchot"
