Step inside Rene Magritte's painting with the use of some common materials lying around the house: one green apple, a bowler hat, an overcoat and some foilage snipped from your fake plant to tie the green apple (somehow) in front of your face. It'll be surreal.
Your mock-up of photo artist Phillip Toledano's creation will give your friends nightmares for weeks. Start searching every Deseret Industries for every baby doll you can find. And pray nobody else has the same idea. This one's sure to be memorable. Materials: dolls and some serious glue.
And finally, Michelangelo's ever-enigmatic Mona Lisa. Paint a really bad copy of her body, cut a hole out for the face, and voila: Art! Materials: paints, crayons, whatever; canvas or cardboard; your face.
