A photo posted on social media a few years ago showing a crowd having fun at a concert has spread across the internet and confused thousands of people again.

At first glance, many think that it is an audience and a stage, that is, a concert, and not a field with cotton and machines.

The photo was taken by Micah Horn, a photographer from Texas who painted cotton picking machines, but did not expect his photograph to go viral and be named the best optical illusion of the year.

Most people in the photo first see the crowd at the concert, but the people are not people, they are actually cotton, and the lights and the stage are actually a cotton-picking machine.

"It took me a while to figure it out," "I still see little people," "At first I thought this was a concert," are just some of the many comments.
