Fourth Grade Optical Illusions

Fourth graders learned how to create an optical illusion artwork just by using triangles and curved lines. The triangles with curved stripes and the curved lines around the triangles give the illusion that the triangles are really 3-d cones coming off the page along with lines that appear to be moving around.

It was a little complicated to "get" at first, but after a few tries the students got the hang of how to draw it so that they would get a COOL effect.
