At first the demo didn't work at all for me. Nothing would happen at all. Then I tried to click on a few buttons, and text started dancing left and right, with no apparent reason.

Then I got better at it. It seemed to reverse the words and letters more or less fine.

Then I spent the $5 on the product for Spanish (could be handy). I'll happily spend another $5 on a French version.

And I know how to impress everyone tomorrow!
