Ambigram- Noun: a word or image that can be read or percieved in many different ways.

In this case, right side up and up side down. And just incase you can't read it because of the wonky stlyized letters, it reads "TYELLE." A former "friend" in high school went nuts over these things for like a month... I hated it because it seemed like he could take anything neat or cool and turn it completely nerdy. I finally got over my aversion to ambigrams after seeing the beautiful one on Paul McCartney's latest album ( http://images-jp.amazon.com/images/P/B000AL730Y.09.LZZZZZZZ.jpg ) and suddenly I had to make one....it's not as elegant....but I like it ^-^
