Do you often forget the things you need at the worst possible time? You’re running late, you’re about to leave your house and, suddenly, your keys. They were right there, but they just mysteriously disappear… Can you count all 29 ovals in this picture?
Sometimes we look at an image and something immediately catches our attention because it is not where it should be. Other times we feel that something is wrong, but we don’t understand exactly what it is and so we have to look more closely.
Then we notice details that we haven’t seen before and find more and more inconsistencies. Okay, that doesn’t usually happen in everyday life, but it does happen in our selection of images with strange errors that are difficult to detect.
