When Nicholas Hanna, a Canadian media artist first moved to Beijing in China, he was impressed with the water calligraphy people created in the parks which involved using a large brush to paint Chinese calligraphy on the road, in water and ofcourse, the characters disappear when water evaporates. Hanna created a cargo tricycle, with a computer-controlled dot matrix water release system, that squirts out passages of Chinese poetry on the road behind him as he rides. Quite interesting isn't it? Unlike graffitti on the walls, there won't any permanent markings on the road, after all, being water, it would disappear when it evaporates.
