The Art of Peeing is a font that was created by its artist by peeing on a wall and capturing the resulting alphabets. New York-based serial wall painter Aravindan Thirunavukarasu used his hips and his man-companion's golden ink to draw alphabets onto an unsuspecting wall, before taking photographs of the results. These photos were then used to generate a typeface and font collection which is available for free download on his Tumblr page. Thirunavukarasu describes his art form as "grappeeti" -- graffiti using pee.
As you'd expect given the manner in which it was created, it's not a typeface for the symmetrically obsessed, but involves plenty of random drips, dots and splash marks. These features actually make the font pretty awesome to look at. If I had to classify The Art of Peeing, I'd say it's more Comic Sans MS than Times New Roman.
While this is one typeface you might not want to use for your PhD thesis, it actually looks legitimately great and might work well for a lot of other applications.
It is not known whether Thirunavukarasu pissed anyone off with his wall-painting exploits, but whether you approve of his modus operandi or not, there's no question that this typeface is unique.
