Ambigrams, Logos, Word Art

http://johnlangdon.net/index.html
"Ambigrams. Logos. Words as art. As both an artist and a graphic designer, I specialize in the visual presentation of words. Language, philosophy, and science are interwoven into the design of words, which are manipulated to create surprising illusions. This unique approach culminates in a wide variety of corporate logos, and in ambigrams– words that can be read equally well from more than one point of view. Most of my ambigrams read the same when turned "upside down," or rotated 180 degrees. If you were to climb up on your desk, walk around behind your monitor and lean way over so you could see the screen, you'd be able to read Wordplay” and my “JohnLangdon” logo just as easily as you could sitting in your chair."
