We have an affinity for — of course — cool optical illusions. This, ladies and gentlemen, is one of them. When you look at this, you would SWEAR that it is a spiral. The lines are obviously moving in toward the center.
But NO, the lines that look like a spiral are actually concentric circles. To prove it, you’ll have to move your eyes along the lines very carefully and slowly, or just use your oily finger to leave a nice grease mark on the screen. Hopefully you have some screen wipes and it’s time to clean that disgusting monitor of yours anyway, right?
