Cafe Wall Illusion

In this fun and interactive online exhibit, the straight lines of a tile wall appear to curve. The learner moves the rows of tiles and changes the color of the grout to achieve the intriguing effect. Although the exhibit requires a computer, the concept can be adapted into a longer, hands-on exploration of optical illusions.
