If anyone ever tells you they don't understand Abstract art, tell them to go take a walk in the woods. This isn't the same as telling that person to "take a hike!"... I literally mean for you to tell them to take a walk in the woods and look around a bit. Nature is very abstract. Here are some "marbleized" leaves created by Mother Nature herself. I collected them on an early morning walk over the weekend. These specimens are from the Birch tree...shapes within shapes, colors within colors, layer upon layer of abstract goodness.
