Here is another cool one for you. There is something about the color gray that can trick our brains. In this picture, the tiles labeled with the dots are actually the same color.
The relative darkness of the tiles around the lower dot tile tricks us into thinking it’s a lighter color, but if you were to isolate the small sections, you’d see they’re the same shade. Our brains are smart enough to understand shadow and light, but we can still be tricked. We wonder if this works with other colors or if it’s only gray that will trip us up.
It Doesn't Matter How Much You Tilt Your Head
We know what you're thinking: two pictures of the Leaning Tower of Pisa. What could be the trick here? Something hiding among the columns? No, take another look. A long look. There aren't two different pictures here – they're the same picture.
The same exact picture. They're oriented the same, and neither of them is tilted. But how? Surely the one on the right is tilted farther? After careful inspection, no, it isn't. Our best guess is the picture on the left creates a new “starting point” for your vision of the one on the right, so it appears to tilt farther.
One of the Classics
If you're a fan of optical illusions, there's a pretty good chance you've already seen this one. If you use your finger to cover up the gap between the two square tiles, you'll discover that the colors of what remains are the same. Try it and you will start getting mad at your eyes and brain for tricking you this way.
Since it appears that light is shining on the upper segment, and the lower segment is in shadow, we think that the upper is naturally darker, and the lower is naturally lighter. But, as we can see, they are the same exact color.
Three Parked Cars?
Aside from the weird motion blur, we just see three identical cars that go from smallest to biggest, right? Wrong, friend. You see, the cars are all the same size. You may scoff, you may laugh, but if you were to place them all in a row at the bottom of the image, they would all have the exact same height.
The trick here is the apparent slope of the road they're on, which makes us think the bigger cars are farther away and, thus, naturally, larger if our brains see them as the same size. In real life, maybe, but in the image, they're copies.
It Needs a Relocation
Why should Paris have the Eiffel Tower all to itself? The Eiffel Tower really isn't all that large. Small enough for a crane to pick it up and plop it somewhere else so the lawn can be taken care of a little bit.
No, we're kidding – while the Eiffel Tower is a little smaller than a lot of people think it is, it's still a thousand feet tall at the tip. Putting a crane anywhere within visual distance of the Eiffel Tower is going to create this fun shot at the right location. Paris's iconic landmark isn't going anywhere, don't worry.
