A few years ago when David and I were on one of our little trips around Texas, we saw this really cool environmental mural on the side of an underpass on the highway. I can't for the life of me remember where it was exactly, but I remembered it when I saw this picture on the internet yesterday.
Well it got me wondering if there was anything on Youtube.com similar to this and I found the same picture as above in a video on Reverse Graffiti. RG is when an artist uses clean rags or power washers to clean off dirt on concrete or metal surfaces to produce a picture without spray paints. It's better for the environment. At least someone is thinking out there.
