This is the Jastrow Illusion, often called the boomerang illusion. Enjoy the delightful dachshund version brought to you by Paul Draper.

This is perfect for family shows, birthday parties, and preschool performances. It is great on stage or close up.

Paul Draper has taken the best elements of all previous versions of this great effect and, with the help of a mathematician and a professional cartoonist, has made a multiple-phase, stand-up version that is easily customizable. You will download the black-and-white images, print them out, color them in so they’re customized for your shows, and perform this effect everywhere you go!
