Optical illusions are popular for very good reasons. They can entertain people no matter how young or old. You can find plenty of them online. The Spin Science Tri-Zonal Space Warper is an illusion toy that used to be sold in 1998. It has a trippy pattern that plays tricks on your eyes as you give it a spin on your desk. Based on our test, this will spin for a minute or two depending on how well you do it.
This is metallic with a pattern attached on top of it. It is heaver than KineticMagnets that we covered here a while back. You will just have to put it on a flat surface and give it a good spin. If you stare at the center for 15 second and then look away, you will see a trippy swirling effect. This was an idea by Jerry Andrus, produced by Binary Arts Corporation.
