Real moving optical illusions

Even when you know how an optical illusion works, it can be hard to convince your senses that what you're seeing isn't real. The best way to demystify an illusion isn't necessarily to read about it—sometimes, you just need to see the image from a different perspective.-->Even when you know how an optical illusion works, it can be hard to convince your senses that what you're seeing isn't real.

The second image in the slideshow is an Ebbinghaus illusion. As the cluster of blue circles gets bigger, the red circle in the center appears to shrink, and the opposite seems to happen when the blue circles contract. Hit the Reveal button and you'll see that the red circle actually stays the same size the whole time; this is the result of relative size perception.-->These moving illusions from Lenstore use clever animations to reveal the mechanisms behind their visual trickery.

In reality, the four lines are all part of the same moving square. The trick behind this illusion is called motion binding: When two sets of objects are in motion in front of you, the movements of one set affect how you perceive the movements of the other. Your brain constructs a pattern for the line movements that doesn't exist.-->The third optical illusion shows four sets of lines, with the parallel lines apparently moving back and forth together.

But at the very least, turning the illusions off in the moving images below should give your brain a break.-->Once the solutions have been revealed, you may still have trouble reconciling what you see with what you know to be true.

The IssueAnyone fascinated with optical illusions has probably wanted to try their own hand at it at some point. Drawing optical illusions, though, can seem pretty impossible, partly because the objects of your art are themselves impossible at times. However, it might be a lot easier to draw optical illusions than you think. Make sure when you don’t deceive yourself when sketching your work.You don’t have to start huge. The secret is to pick a simple optical illusion to draw. And, even some seemingly complicated optical illusions are a lot easier to draw than you’d think. Take today’s illusion, for example…The circle in the middle of the paper appears to be moving or hovering, doesn’t it? Well, it’s pretty simple to recreate this illusion on your own. All you need is some graph paper, a pen, and something to draw a perfect circle to be on your way to draw optical illusion images!Here are more inspirations.See how easy it is? Now, get artistic and give it a shot!Enjoy finding out how to draw optical illusion images? Head over and check out this awesome video on the making of an optical illusion hole!We feature our reader’s work all the time. These were drawn by Jovert Ante and he eagerly wanted to show us.

Every year in Geometry, I spend a class period “playing” with optical illusions. I usually spend one full 45-minute lesson on optical illusions (bellwork, homework questions, and everything as well). I know that there usually isn’t a lot of time for fun because there is so much pressure around testing.Why I Teach About Optical IllusionsI think that this lesson serves an important purpose in class and just in life in general. The main objective that I’m trying to drive home with this lesson is that you can’t always trust your eyes. I talk about how in math (and in life!), we can’t just take things at face value, they must be proven. Also, we can’t just make up our own rules, they must be agreed upon rules/laws/theorems so that everyone can come to the same conclusion. I use optical illusions as a fun way to drive this point home.I teach this lesson at different points in the school year, depending on what I feel like doing that year. I do this lesson at one of three times in the year.The first day of school (as a fun intro to Geometry)Sometime in the first week or so of school (usually right before I introduce congruence)Right before we start proofs (and I emphasize the point about proving things with rules)How I Teach Optical IllusionsFirst, I tell my students that we are going to have a different kind of day that doesn’t require them to take notes. I let them sit on the floor, sit on their desks, or get comfortable (by this time, they are SUPER interested). Then, I tell them that as long as they are being respectful, raising their hands, and participating, there will be no homework. I usually don’t make kids raise their hands, but they tend to get a little excited by the end of the lesson and want to call out, so I make that a requirement for the day.I have a powerpoint with all types of optical illusions that I show the students (click the link to download). The first picture is below. I show them

His picture and ask them not to comment. After a few beats of silence, I ask someone for their comment about the pictures. We talk about seeing the vases vs. the faces.I continue through the powerpoint in this way. I always ask for silence first, then a few comments, then let them discuss amongst themselves for a second or two until everyone sees the picture. The old vs. young woman is always a favorite.As the slides progress, they get more geometric. At this slide, I make them prove to me that the lines are straight. I’m annoying enough about it that an exasperated student will finally get up and find a straightedge (book, ruler, binder, etc) to prove it to me.This slide is where I talk about our eyes playing tricks on us. Some students pick this up right away, and some take forever to figure it out.Once we finish going through the powerpoint together, I talk about the importance of proof and not making assumptions. Then, I give this handout (click to download). A few types of optical illusions are explained and there are a couple of good websites linked at the bottom. Sometimes, I just project the handout and we discuss it that way.At this point, there are a few things you could choose to do for classwork if you have extra time. I never do, but I usually have one of these activities ready to go, just in case. Students could...use their devices to search about M. C. Escher. Maybe they could write a few sentences about how he used optical illusions in his work.find another optical illusion and write about how it tricks the eyes.work review problems.work on an optical illusions worksheet.

Hey Friends!It’s so great to have you back again! I hope you’re ready to learn something inspiring today, kiddos!Today we are going to learn about something super fun to look at because it makes our eyes trick us. They are called illusions!Illusions are pictures that have the power to trick our minds into thinking we’re seeing something that is different than what is really there! Sometimes illusions get really popular because of how good they are at confusing us!Artists always have a good time using illusions in their work! If you think about it, most paintings are illusions, too. Artists can trick our eyes and make a flat piece of paper look three-dimensional, or 3D, and real.In this video, Dr. Matt McMahon explains how optical illusions work. Illusion artists are all over the world and making different kinds of art. The one who made this one is from a country far from where we are.Let’s take a trip all the way to Ukraine! There we would find one the coolest illusion artists. He is 52 years old and makes pictures that show different pictures at the same times.If you focus you can see a white Ram with horns. But you can also see a man with black hair and a long twisty mustache.How awesome is that? It’s like two pictures in one!What colors do you see in this picture?Do the colors influence what you see?Paintings are illusions, too, because they can make something flat look round. Sometimes, a drawing or
