Seattle based artist Peregrine Church has created an awesome series of water-activated street art called Rainworks. On sunny dry days, Church takes to the streets painting images with an environmentally friendly spray-on sealant that repels water and lasts anywhere from four months to a year.
It appears that the concrete below is a blank canvas, until the rain hits to reveal the negative of his art. You might even remember doing similar projects in school with crayons and water color.
His artwork send positive messages and spreads support of the environment for everyone to appreciate.
Check out the more art and the video after the break.
