At first glance you might think you’re looking at a huge concert crowd but it’s actually a photo of several industrial cotton harvesting machines at night. The photo was taken by @micah.b.horn on Instagram and the image quickly went viral after being posted on reddit.

Don’t feel too bad, a programmer had the brilliant idea of running the photo through Google’s Cloud Vision API and even the machines were fooled! The top three results were ‘crowd’, ‘festival’ and ‘stage’.
