You are watching something that could be dangerous. But you are safe, the watched object is behind the bars. You feel empowered, so you get very very close. You can see every possible detail.Pixel by pixel.Getting so deep into the details prevents you from viewing the whole object. You can't recognize what the object is, because it is so pixelated. And still you don't want to move away, you are afraid to loose your "advantage". Information overload is as bad as lack of information.
