As an art historian of Precolumbian Mesoamerican cultures and a supporter of Barack Obama, I have to admit that I found this to be very cool. David Stuart, a world renowned Maya epigrapher from my alma mater, the University of Texas at Austin, designed a Maya glyph that spells "Obama".
If you are wondering about the additional "a" at the end, this is a result of the way Maya words are constructed. This glyph block is created by four glyphs that represent individual syllables (click on image to identify individual glyphs). The Maya syllables are either a vowel or a combination of a consonant-vowel sound. The Maya words therefore are formed with alternating consonant-vowel-consonant constructions. Also, the last vowel sound in the word is not pronounced, so if you only had the first three syllables, o-ba-ma, it would be read "obam". This is why the additional vowel of "a" is added at the end, so that when read the final vowel sound in Obama will be preserved.
