Cultural Optical Illusion

This sketch is interesting because what it shows can vary depending on the cultural background of the observer. To those in the west who are used to being indoors this picture can appear to show a family sitting in the corner of a room with a window through which vegetation can be seen outside. Show the same image to someone in Africa however and the perception changes, the rectangular room corner looks like a tree and the window appears as an object being balanced on the woman's head.
