Last week Kaler students got to practice making some optical illusions using construction paper and black markers. They were given the challenge of cutting out at least 5 shapes from scrap construction paper, gluing them to the paper and then trying to outline the shapes with lines. As the outlines got bigger, they would run into the outlines of other shapes creating an illusion of movement. Some students even took it a step further by turning the shapes into faces.
