The Now Never ambigram shown here is a nice short asymmetric ambigram that displays the flexibility of the ambigram generator.
Since it is an ambigram, this design reads 'Now' when upright and reads 'Never' when upside-down.
For a mental work-out, try to read it upside-down without rotating it (you can mouse over it at any time to make it spin).
To view this asymmetric ambigram on everything in the FlipScript store, you just need to use the menu bar at the top to navigate to an item and every product will display the Now Never ambigram.
