Seattle Public Art Project Only Appears When It Rains...

...So, basically all the time.

Seattle, one of the rainiest cities in the United States, could use some cheer. The gray city of grunge recently turned one of its most well-known handicaps into an attraction with Rainworks, a series of street art pieces that appear only when wet. Created with what functions as a sort of invisible ink made from a biodegradable, environmentally friendly, water-repellant coating, images ranging from a computer error code to a faucet have been stenciled onto the city’s sidewalks. Once it rains, and the concrete gets soaked, the stenciled work “magically” stays dry—and the images make their presence known. According to CityLab, the project was spearheaded by local magician Peregrine Church who, along with friends Xack Fischer and Forest Tressider, has painted 25 to 30 of these “rainworks” around the city (you can view a full map here). Church hopes that the pictures will help bring a little joy to the weather-embattled city, which saw more than 48 inches of rain last year.
