Just because you're not an artistic person, doesn't mean that you can't make a fun art project. SF Globe is happy to show you this quick trick. It's fun and easy. 


All you need is a piece of paper, a handful of markers and a hand. Kids will love making this in a variety of colors. It also will help develop fine motor skills in younger children. Try this with other objects and see what kind of effect you can create.

This optical illusion works by taking advantage of the way our eyes process visual information. Many neurons for vision are specifically keyed into looking at how edges are oriented. That information is used to build the shape of an object. The sudden breaks in the straight lines is what makes your eyes believe it's seeing a 3D image.
