Taking the idea of "the medium is the message" to the extreme, the designers of the South Korea Pavillion for the Shanghai Expo created a building literally made of words. Composed of 25,000 panels which will be sold off individually at the end of the event, the characters are Han-geul letters from the Korean alphabet.
According to the organizers, all sales proceeds will be donated to a foundation advocating minority and multiculturalism in Korea. You can see more art and animation that led up to the structure's completionhere.
