This tutorial shows you how to create fun and impressive Optical Illusion art using a pen, pencil and a ruler.

This is a great cross curricular art and maths lesson that will support your pupils with ruler skills, focus, measuring and understanding Op - Art and shading. It works if you are looking at how to create 3d shapes or studying the work of M.C Escher.

This activity does not take any planning or resources and is particularly great for KS2 students.
