Impossible? No, just unlikely.
The fairly long Products Ambigram displayed to the left is a nice example of an engineered optical illusion at work.
As you can see from the preview, this design says 'Products' one way and also says 'Products' the other way (or is it the other way around?).
If you wish to see the design inverted, simply move your mouse cursor over the graphic.
All items in the FlipScript store are already displaying the Products Ambigram. To see them, click on one of the categories in the red menu bar above and you will see the Products Ambigram everywhere! Don't forget that you can change your mind (and your design) at any time by using the 'Create New Ambigram' button on the top of every page.
