Necker cube

The Necker Cube is a simple optical illusion that appears as a three-dimensional cube drawn in two dimensions. When you look at it, you might see the cube oriented in one way or another, but it can switch back and forth between perspectives. This happens because our brain interprets the flat lines in different ways, leading to the perception of depth. It's a fascinating example of how our visual system constructs reality and illustrates concepts in perception, psychology, and cognitive science. The Necker Cube highlights the brain's role in making sense of ambiguous visual information.
