Can you see it? Look again. No, really. Look closer. See it now? Yes, it's a brick wall. But it's also something else. The latest optical-illusion challenge to sweep the Internet is a seemingly dull photo of a pretty ordinary brick wall.
UK resident Arron Bevin posted it to his Facebook page on Monday with the message "This is one of the best optical illusions Iv seen." You can't look away until you've sorted out what's going on.
The Facebook post now has nearly 30,000 shares and over 42,000 comments. The discussion even spilled over to Twitter, where people are saying things like "it took me SOOOO long to get that brick wall optical illusion thing. So obvious now hahaha" and "Once you see the illusion in this brick wall you'll feel you've achieved everything in life."
