Impossible? No, just unlikely.
The nice short Hate Love ambigram displayed to the left will look good on just about any product in the FlipScript store.
A quick glance will show you that this typographical marvel says 'Hate' one way and says 'Love' 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.
All items in the FlipScript store are already displaying the Hate Love ambigram. To see them, navigate to a category using the red menu bar above and every product will display the Hate Love ambigram.
