I had to stare at this for a few minutes. Via Neatorama.
The blue elements in the image above appear to be a arranged in a continuous spiral, but in fact they form a series of concentric circles. Your brain will argue so strongly for a spiral that you may need to run your mouse cursor around the circles a few times to convince yourself.Read the rest
Kokichi Sugihara's Ambiguous Cylinder Illusion was a finalist of the Best Illusion of the Year Contest 2016. Do you know how it works?
After watching Ben Ridgway's "Continuum Infinitum" video, everything I looked at seemed to recede for a while. Ben recommends downloading the video and looping it.

As you watch the movie for a minute or so and then look away, you will experience a mild optical illusion that feels as if everything you look at is shrinking away from you. This is caused by the motion after-effect (MAE). It is a visual illusion experienced after viewing a moving visual stimulus for a time (tens of milliseconds to minutes) with stationary eyes, and then fixating on a stationary stimulus. The stationary stimulus appears to move in the opposite direction to the original (physically moving) stimulus. The motion aftereffect is believed to be the result of motion adaptation.
Neurons coding a particular movement reduce their responses with time of exposure to a constantly moving stimulus; this is neural adaptation. Neural adaptation also reduces the spontaneous, baseline activity of these same neurons when responding to a stationary stimulus. One theory is that perception of stationary objects, for example rocks beside a waterfall, is coded as the balance among the baseline responses of neurons coding all possible directions of motion. Neural adaptation of neurons stimulated by downwards movement reduces their baseline activity, tilting the balance in favor of upwards movement.
"This is an amazing piece of 3D art [by Patrick Hughes and on display at Birmingham Art Gallery] where the closest part of the picture appears to be the furthest away, an optical illusion known as "Reverspective". As you move around the painting, the room in the painting appears to move with you." Read the rest

Can you spot the baby in this image? Researchers at the Universities of Cardiff and Cambridge found that volunteers who showed early signs of psychosis were much better at recognizing the baby than a group of people who did not have psychosis.
Can't see the baby? Good for you! See the original photo.

It looks like 2 interlocking wire spirals. In your hands, the two spirals seem to wind together or wind apart, completely effortlessly. However when you hand the Mephisto Spiral over to someone else, they find that they cannot replicate the action – the two wire spirals are completely rigid.
Alternatively, by simply moving your hands in one direction, you can make the two spirals appear to unwind, yet however many times you repeat the action, the two spirals never come apart.
