The modified tricycle mimics the Chinese custom of writing temporary messages on the road with water. With a computer installed on the handlebars, the water calligraphy device allows the rider to type Chinese characters, which will be transmitted electronically to a set of valves, which release water droplets in programmed patterns... Thumbs up for this nice invention!
