Derek from Veritasium uses his body to demonstrate an set of windows that appear to start rotating in one direction, slow down, then change directions, despite constantly rotating in just one direction. He then goes on to explain how the Ames window illusion messes with our brains, and why it doesn’t work for everyone.
THE BEST Optical Illusions
Mathematician Kokichi Sugihara of Meiji University shows off another brain-breaking optical illusion, taking home the prize of Best Illusion of 2020. While it looks like a simple design at first, the 3D Schröder Staircase looks exactly the same right-side-up and upside-down, its left end looking taller than its right.
We’ve seen lots of optical illusions over the years, so we’re always excited when we come across one we haven’t seen before. Twitter user jagarikin posted this mindbender, which makes it appear that the spinning circles are moving around, despite being stationary. Don’t believe that the circles aren’t moving? Check this out.
Animator and illustrator Vier Nev describes A Mind Sang as “a short film about perception, rebirth and transformation.” But it’s also a wonderful exploration of optical illusions and the phenomenon known as Pareidolia, or humans’ tendency to see faces and other body features in places where they aren’t.
When you place clear glass into certain kinds of oil, it can eliminate refraction and reflections, making it appear invisible. A few years back scientists from Japan’s National Institute for Materials Science decided to build a Rube Goldberg machine that takes advantage of this illusion, complete with invisible steps and ramps.
We shoot a lot of video inside of cars looking out the windshield. But the in-car footage often makes it look much slower than it felt zooming around the track. After watching this clip from Akiyoshi Kitaoka, we realize just how much of a difference having a wide angle lens makes when it comes to the perception of speed.
Each of the 54 cards in designer Gianni Sarcone’s deck features an original illustration that will mess with your mind. Each image combines the card’s value and suit with a trippy optical illusion. The set comes packed in a rainbow-sheen holographic tuck case.
Take a look at the video, and you’ll swear that these balls are spinning in a circular orbit. But look more closely, and you’ll see that each ball is moving along a perfectly straight path. The mechanical model is based on a design by 16th century Italian poymath Girolamo Cardano.
DONG host Michael recently visited Sydney, Australia and noticed a strange optical illusion – the famed Sydney Opera House looks like it gets larger the further back you stand from a window looking out at it. Apparently, it’s related to the size and position of an object’s frame.
