Famous for its notoriously rainy weather, Seattle is the perfect home for this new series of water-activated interactive artworks, illustrations, and hidden messages that only appear when wet. Titled Rainworks, the invisible pieces by Seattle-based artist Peregrine Church started popping up last year. Each installation is made from an environmentally safe, water-repellent coating that lasts anywhere from 4 months to a year. You can see more here. (via Vandalog, Metafilter)
