Have the students create an original artwork. It can be watercolored or whatever medium you feel like using. Take a picture of the artwork and have the students choose two effects on the computer to enhance their photo. I used photo shop. The original picture is in the middle and the two added effects are on the ends. It's kind of hard to see how cool they are from the picture. They look way better in person. This was one of our art displays for our schoolwide art walk.
