Impossible objects, like those drawn by artist M. C. Escher, don’t seem like they could exist in the real world. But Kokichi Sugihara from Meiji University in Kawasaki, Japan, is well known for building 3D versions of these structures.
Now a new video shows his latest construction: a gravity-defying roof that seems to attract and balance balls on its edge. When the house is rotated, its true form is revealed.

Did somebody say optical illusion? This is a classic illusion explained. 🙂
In 1934, ophthalmologist Adelbert Ames, Jr. devised a room that pushes the boundaries of human perception. Visit a virtual version of the now famous Ames room, as Scientific American Mind editor Ingrid Wickelgren explains how it works.
If you know me you know i like a good illusion. Exposing flaws in the brain is fun!
Here is a good one from Mighty Optical Illusions
Keep staring at the flashing green dot, and the yellow dots will fade or disappear due to motion-induced blindness.
As many of you know, i LOVE optical illusions. Not just because of their visual impact, but also because of the insights it can give us into the workings of our brain, another favorite topic of mine.
This is one of my favorite YouTube channels because they always post something interesting.
Check it out. 🙂

I just found an optical illusion that actually threw me off a little bit. I stared at this image, wondering what the optical illusion was and I came close to closing out of it and dragging it to the recycle bin, but I decided to post it. I was a bit shocked when I realized what happened. Stop reading this text right now, scroll down and patiently watch this optical illusion and you’ll see exactly what I’m talking about. No cheating, go look right now!
Now, this is a pretty cool picture and it’s taken from a movie that I really enjoy: The Shining. You see, I’m a pretty big fan of horror movies and this is definitely a creepy movie. If you’re a fan of horror movies, you’ll know that this is a classic one. Even though I liked this image, I didn’t know if it would work well on the site, but then I remembered that this is actually an optical illusion. You see, these are called cinemagraph optical illusions. If you like this image, you should use it on a message board or anywhere you’re active online. It will definitely catch people off-guard and they will love it.
In which direction does this #train move? From which end of the tunnel is it arriving from? It might be both! Check if you can “see” a different direction each time you look at it? If you stare long enough, you might even make the train change its course. Today’s illusion works in the same manner, our famous Spinning Girl does. After all, there is no definitive answer, since the animation loops through just a few frames. On the other hand, if you recognise the station, you just might know the true answer after all 😉

The brain’s perception of the body may seem set in stone, but a new study shows the mind can be tricked into taking an entire virtual body for its own.
In 1998, neuroscientists Matthew Botvinick and Jonathan Cohen performed an experiment where they showed people a rubber hand being stroked with a paintbrush, while applying the same strokes to each person’s own, hidden hand. This gave people the feeling that the dummy hand was their own.
Scientists have since demonstrated the so-called rubber hand illusion for other body parts — and even whole bodies. Often this is done by putting people in virtual reality settings.
“It seems the brain, under certain conditions, quite easily accepts the idea that [a virtual body] is your body,” said study author Mel Slater, a computer scientist at the University of Barcelona. [Eye Tricks: Gallery of Visual Illusions]
In the new study, Slater and his colleagues investigated whether taking ownership of a full virtual body resulted in neglect of the real body.
Study participants wore head-mounted displays in which they saw a virtual body when they looked down at their real body. Half of the participants experienced a realistic body illusion, where the virtual body’s posture and movements matched those of their real body, while the other half experienced an unrealistic one, where the posture and movements didn’t match their own.
The researchers had the participants place their hand on a cooling device, and measured participants’ sensitivity to small changes in temperature as they experienced a realistic virtual body illusion or an unrealistic one.
During the rubber hand illusion, the real hand has been shown to cool down, suggesting the brain pays more attention to the rubber hand. The researchers suspected that if people were neglecting their real body in favor of the virtual one, sensitivity to temperature changes on their real hand would diminish.
But the opposite was true: People remained sensitive to temperature changes when they experienced a strong illusion that the virtual body belonged to them, and became less sensitive when the illusion was unrealistic. In other words, the better the illusion, the more aware people were of temperature changes in their real hand.

This trick train video is from neuroscientist Al Seckel, who says that it’s of an actual model train going into a tunnel, without the benefit of any computer tricks. So what’s really happening in this optical illusion?

These chairs are something you do not get to see every day. Collection titled “The Hidden Chairs” by French design studio Ibride provides this beautiful, intriguing animated optical illusion you see on your right. It blew my mind first time I saw it! All of the chairs from mentioned collection look irregular and warped, but when you see them from a specific angle, their shape will remind you of the classic design.
When you see each of the chairs from a specific angle, you might easily mistake the right way to sit on them. Gallery below depicts this perfectly! The Hidden Chairs line includes three beech plywood chairs that follow three historical designs: “The Hidden Shaker”, “The Hidden Terence” and finally “The Hidden Wagner”.
Paris-based design trio Ibride comprises graphic designer Rachel Convers, designer Benoît Convers and editor Carine Jannin. The furniture was shown at Maison&Objet design fair in Paris, which finished last week. Let’s see if they manage to trick you as well!
