How do you feel about optical illusions? Maybe you’re a pro and you’re here to show off (if so, good for you!). Or maybe you’re a brave sort and have joined us to give yourself a much-needed challenge, a “study break” to keep the old cerebral cogs turning. If so, welcome! Let’s begin.
Take a look at the seemingly one-dimensional pattern below. What do you see? Black and white lines and boxes; a panel that looks a little bit like a brick wall, correct? Well, look again! If you didn’t see it straight away (and don’t worry, many people don’t), there are actually sixteen sneaky circles hiding in this complex optical illusion. And it’s no amateur effort; this image was first shared as one of the top ten best illusions in the 2006 Neural Correlate Society’s “Best Illusion of the Year” contest.
