Nicholas Hanna’s Water Calligraphy Device

Nicholas Hanna’s Water Calligraphy Device

In China, there is a tradition of street art in which an individual uses a brush dipped in water to write out messages or poetry. This leaves a very temporary mark which disappears as it evaporates. Beijing-based artist Nicholas Hanna wanted to take it a step further and automate the whole process.

In China, tricycles are used quite frequently and converted for all kinds of utilitarian purposes. He added water tanks and a computer system that controls an array of solenoid valves. A laptop is mounted on the handle bars used to type whatever message he wants. It’s then sent to the solenoid valves and sprayed onto the street in water. An ephemeral and interesting message is left in the tricycle’s wake. Hanna’s tricycle will be making its rounds through Beijing until October 2nd as part of Beijing Design Week.
