The Dynamic Ebbinghaus

1srt prize winner of the 2014 Best Illusion of The Year Contest

The Dynamic Ebbinghaus takes a classic, static size illusion and transforms it into a dynamic, moving display. A central circle, which stays the same size, appears to change size when it is surrounded by a set of circles that grow and shrink over time. Interestingly, this effect is relatively weak when looking directly at a stationary central circle. But if you look away from the central circle or move your eyes, or if the entire stimulus move across the screen, then the illusory effect is surprisingly strong — at least twice as large as the classic, static Ebbinghaus illusion.

Flexible colors

One colored image can lead to several color perceptions, depending on the position of black outlines that are presented on top of the colored image. The shape of a surface depends more on changes of luminance in the visual scene than on specific colors themselves. By presenting black outlines on top of colored images, the whole area between outlines is seen as having one single color. Instead of seeing the actual colors presented at each location, our brain prefers to see one homogenous color, as surfaces in real life are usually also perceived with one single color.

A Turn in the Road

Short description of our illusion: When we look at two pictures that are physically the same, they usually look the same. When they are different, they look different. Our illusions show the opposite: two images that are different but look the same — those are called “metamers”; — and two images that are identical but look different — we call those “anti-metamers.” Our main illusion mixes the two: it shows three images, two of which match with a third one mismatching. Viewers see one image as odd, but it’s one of the two identical images they see as different, an illusion we call “false pop out.”
