That was easy ;-).
The nice short Mason Ambigram displayed to the left is just one of the infinite number of ambigrams that can be created on the FlipScript site.
Take a look to the left, and you will see that this typographical marvel says 'Mason' one way and also says 'Mason' the other way.
If you wish to see the design inverted, simply move your mouse cursor over the graphic.
If you wish, you can create other ambigrams by clicking the Create New Design button here.
