Creative Exercises for Artists and Art Students

I read on Free Technology For Teachers about a blog for Artists or Art students. I don't know about the Anchorage School District but out here in the Valley they do not have an Art Program, it makes me very sad to know that they don't have one and that art is put on the shoulders of teachers. But this website give teachers ideas for art. Some are really neat! I really liked the three strikes your out project. What you do is take your pen or pencil or whatever you want to create with and make a picture using only 3 lines, you can draw a tree and a river and a mountain or whatever you want. The possibilities are endless. I would like to hear what you all like or even other options for Art in the classroom.
