There's several universities in my area, but the closest is Hongik University (????????). It's predominantly an art school, and as such, has its share of bad boy artists. Some of them work delivery over at the nearby LG foodcourt, sporting things like pink hairdos, spikey belts, and other punk attire. Other bad boys are getting into graffiti which has been showing up more often.
One such "artist" has apparently borrowed a play from Marcel Duchamp's book.

From your link: "In December 2004, Duchamp's Fountain was voted the most influential artwork of the 20th century by 500 of the most powerful people in the British art world."
Unbelievable.
I still like it better than "Fine Art" on a garage, though.
Off-topic: Looks like I'm going to have to clean my sensor for the first time (for those of you unfamiliar with the wide world of DSLRs, there's nothing dodgy with that last statement). I've been researching on how to do it - as usual, everyone says something different. Have you done it? Any ideas?
I've always found Duchamp amusing since I learned about him in college art history class way back in the day. I even thought it was pretty cool when I saw on of his urinals at a museum in Europe.
As for sensor cleaning, a simple manual air bulb has worked fine for me.
