edvard munch (spelling is questionable) "the sream" it is the realisation of the futility of existence. You will find lots of good analysis on the net for the painting, better than I could do. but to help you link it to change, it is the moment of realisation that our existance is futile there is no point to life or something like that. Look, the analysis you find wont specifically refer to change but when you get a grasp of the key idea behind the painting you can manipulate the meaning towards change. More importantly it has techniques that are easy to understand like the way the face has been distorted (changed from the normal shape of a face that demonstrates the horror of the realistaion.) also it is postmodern I think teachers like postmodern because they all studied that at uni even some of the really old teachers.
