Reddit loves a good optical illusion, and the newest trick for your eyes stems from a seemingly simple photograph (taken by Daniel Picon) of a truck driving down a road. We're looking at what appears to be two images of the same road taken from different angles. But, in reality, this is actually a case of the same photograph placed side by side.
Can't believe that these roads are parallel? The simple way to see that the images are the same is to hold your hand over the photos, covering up everything below where the curb ends. In doing so, you'll see that the truck on the right isn't speeding along on a collision course into the left image, but that they are identical. The more you move your hand down to reveal the space at the bottom of the photo where the curb ends, the more the road on the right appears to angle into the image on the left.
But if that still doesn't work for you, here's some proof pulled together by a helpful Imgur user. By separating the images, and stacking one on top of the other, it's much easier to see that what we're looking at is identical.
Still not convinced? This motion graphic demonstrates that the photographs overlay perfectly.
