The Water Calligraphy Device (水!法器) by Canadian artist Nicholas Hanna consists of a modified tricycle that mimics the Chinese custom of writing calligraphy or temporary messages on the road with water. A computer strapped to the handlebars of the Water Calligraphy Device allows the rider to type the Chinese characters they wish to spell out. These characters are transmitted electronically to a set of valves which release water droplets in programmed patterns as the trike moves forward. Two large containers positioned at the back of the device store the water. The Water Calligraphy Device (水!法器) is inspired by the Chinese custom of writing calligraphy in public spaces with a water brush as a contemplative and poetic act.
