You can find so many interesting sites on the Internet that no one is probably going to be surprised if I say that you can use it also for writing upside down and backwards.
I have received funny email written this way from a Mexican fellow blogger Armando Halbinger Perez.
So, if you would like to write e.g. your next blog post or email this way as well just go to this website.
Put your text in the "original" window provided and you´ll see it´s "flipped" version straight away. Enjoy!
