I continually question how artists can impact the world in a profound way. Today I came across an answer in Lily Yeh. Through an unexpected opportunity to transform an inner city lot, she went on to do the same in a massive dump site in Nairobi where 100,000 people live and then to build a Genocide Memorial in Rwanda. Seeing the memorial, people said, "When we see beauty, we see hope. Our loved ones can some home in honor and dignity." Lily explains that through art, we travel to the "dustless world" a sacred place of pristine beauty and poignant serenity." This is her Web site. http://barefootartists.org/. There is a documentary on her called The Barefoot Artist.
