The Water Calligraphy Device conceived and realized by the designer Nicholas Hanna is inspired by the Chinese custom of writing calligraphy in public spaces with a water brush as a contemplative and poetic act. Calligraphers writing passages of poetry, surrounded by a group of onlookers, are a lovely presence in Beijing parks. The Water Calligraphy Device combines the inherent beauty of an ancient form of writing, a refined public art practice with the mystery and magic of mechanisms. The device is mounted on a flat-bead tricycle which is a ubiquitous form of transportation in Beijing. Passages of Chinese characters are input to a computer. Custom software on the computer processes the characters and transmits them to an electrical system that actuates an array of solenoid valves. The valves release droplets of water on the ground as the tricycle moves forward, thus forming Chinese characters that slowly pool together and eventually evaporate entirely. Do not miss the video!
