Friend Wayne asked for more street art pics, so here you are Wayne, including some "Rainworks".
Two street artists, Peregrine Church and Xack Fisher, decided to do something to cheer up members of the public when it is raining. They call it “Rainworks” and it is rain activated art, symbols and messages that only become visible when wet, either by rain or hosing. They use a product called Always Dry which is water resistant and lasts for up to a year, but is non-toxic and biodegradable, so doesn’t cause any damage. Their art has been confined mostly to the Seattle area, here are some examples.
How it’s done:
