Who would have thought that a person could or would have made a water device to write calligraphy?

It seems that Nicholas Hanna, nicholashanna.net, a Beijing-based media artist, has done exactly that. Inspired by Calligraphy artists doing water calligraphy in Beihai park, Beijing, he has reinterpreted the Chinese tradition of using water and brush to write poetry in public spaces by transforming a flat-bed tricycle into a poetry-writing device.

In his video he explains why he did it and how it works.
