It's one of a kind.
The Serenity Ambigram shown here is a fairly long symmetric ambigram that can be viewed upside-down by simply rolling your mouse over the design.
As you can see from the preview, this typographical marvel says 'Serenity' one way and also says 'Serenity' the other way (or is it the other way around?).
If you can't read upside-down (without breaking your neck!), rotate the entire design by mousing over it.
If you wish, you can create other ambigrams by clicking the Create New Design button here.
