Marin County-based photographer Jerry Downs captured the following photograph of two cows standing near each other in Idaho. In the dimly-lit photograph, it appears that the two cows share the same body with a head at each end. In trying to figure out which legs belong to each animal, I am reminded of the strange legs illusion that was posted last year.
I have seen a few cow optical illusions, but this one is one of my favorite. The best part is that it is a completely unaltered photograph.

On Tuesday’s episode of NBC’s show America’s Got Talent, a performer named Special Head wowed the audience by levitating in mid air. During his preparation for the stunt, a bored Howard Stern gave him his sign of disapproval by buzzing him and giving him an ‘X’. The other three judges held back and let him finish his routine. After witnessing the full stunt, Stern decided to change his mind and take his ‘X’ back. Another judge, Howie Mandel referred to it as a “premature x-ification”. See the performance for yourself below.
This illusion concerns apparent rotation generated by pure translation. Square patterns consisting of four segments appear to rotate when they move straightly at a constant speed across the grid background. More surprisingly, the rotations in opposite directions can be generated by exactly the same square patterns. This illusion might be explained by the well-known inchworm illusion which arises at the four segments one after another resulting in the impression of rotation. This illusion is new in the sense that the rotation is generated by pure translation.
This illusion won 1st prize at the 2013 Best Illusion of the Year Contest. It was created by Jun Ono, Akiyasu Tomoeda and Kokichi Sugihara.
This stereogram is a little different than others that have been featured on An Optical Illusion in the past. Previously, the images have mostly contained an image that is hidden in a random and repeating pattern. This type of stereogram is called an object array. If you stare at the six bottles in this below they will become three-dimensional and the image will have depth, but no special hidden image will appear. 3Dimka, the artist who created this stereogram, cleverly calls it a Beerogram.
Presented below is a video that was another finalist for the 2013 Best Illusion of the Year contest hosted by the Neural Correlate Society. The video shows four yellow circles spinning at the same speed around both the Roadrunner and and the very hungry Coyote. Watch what happens when the four circles spinning around the Coyote are replaced with eight. They are still moving at the same speed, but your brain perceives them to be moving much more rapidly. When four more are added, to bring the total number of circles to twelve, they seem to move at an even greater speed.
This video was created by Alan Ho and Stuart Anstis from Ambrose University College, Canada, and UC San Diego, USA.
This grouping of impossibly-connected hexagons was created by tee shirt designer Flying Mouse (aka Chow Hon Lam). This design was originally submitted for a tee shirt design on the Threadless community in 2007. Flying Mouse’s tees have proven to be tremendously popular and have won many prestigious awards. Nearly 100,000 people have purchased a tee shirt featuring one of his designs.
