I'm in a wonderful art group where we share our talents with each other in round-robin style. One of the things we're working on is graffiti-style work based on the book Walls. Inside the book are lots of pictures of - you guess it - all kinds of blank walls, just waiting to be defaced.
We could have taken pictures of walls and then just drawn on them - perfectly good idea - but the book wasn't very expensive and we wanted to patronize the author for coming up with such a great concept. Here are two photos of wall art I created. So much fun!
