The fairly long Calculus Statistics ambigram displayed to the left is just one of the infinite number of ambigrams that can be created on the FlipScript site.
See this example of how you can read this as 'Calculus' when the design is upright and as 'Statistics' when the design is inverted (or is it the other way around?).
If you wish to see the design inverted, simply move your mouse cursor over the graphic.
