Math puzzles can drive anyone crazy, but optical illusions are a whole other level. If you lost your mind over this brick wall illusion a few months ago, you're about to give up on everything after trying to find a mobile phone in this photo.
Facebook user Jeya May Cruz posted the photo on July 2, and it continues to bubble up on people's news feeds for good reason; the cell phone is nearly impossible to find. People apparently feel the same way, considering the post has more than 141,000 reactions and 18,000 shares. Try to find it for yourself below.
Do you see it? It's OK if you don't — it took a savvy POPSUGAR editor to find it, and even then, we still couldn't believe it. The cell phone is by the right leg of the table. You can see the camera and floral case.
Can't get enough of illusions? Try one that tests your vision.
