The fairly long Beautiful Ambigram displayed to the left is a nice generic design that makes you do a double take.
A quick glance will show you that this typographical marvel says 'Beautiful' one way and also says 'Beautiful' the other way.
If you can't read upside-down (without breaking your neck!), rotate the entire design by mousing over it.
If you like this design, here is more good news. You can purchase anything in the FlipScript store with this design. All you need to do is to use the menu bar at the top to navigate to an item and every product will display the Beautiful Ambigram.
