During our museum visit, my husband and I stumbled upon a display called The Unseen, featuring The Light of Optical Illusion. The artwork radiated black and white lines from a central point, creating a striking sense of depth. My husband stepped in first to try it and then showed me where to stand. I positioned myself as he instructed and looked straight at the display. At first, everything appeared pitch black. But as I focused, a stunning black circle emerged, surrounded by white radiating lines that seemed to pulse and move. The illusion was so distinct it felt like staring into a black hole or witnessing strong sunbeam. I was totally delighted by how a simple arrangement of black and white lines and light could trick the eyes, turning a flat surface into a dynamic, three-dimensional experience.
