Abstract :
NO, YOU??RE not going mad; what you should see on our cover this month is dots between the corners of the squares, blinking and flashing as your eye moves over the page. Sometimes I find it works well, sometimes not so well. Here in the editorial office everyone describes what they see differently. I would say there are grey dots overlaying the white ones, but each disappears when I focus on it. Other people describe it as seeing white dots when they focus on them but these disappear when their eye moves away
