I guy name Peregrine Church from Seattle has developed an art that you can only see when it is wet or when it rains. How cool is that? He designed this art so people would have a better day in the rain. I think that it is brilliant. I cannot even imagine the things people would write if they could. All of his messages are made for you to smile. What would you write with Rain-works on Tri-Cities sidewalks if you could? 'Rock n' Roll' would be my first message!
