Shapes look different when you move because the way they fit in your eyes changes. Imagine looking at a basketball on a table, it looks round. Now walk away and the ball still looks like a circle, but if you tilt your head or move closer, the shape might feel stretched or squished. This is how our brain understands distance and position.
Examples
- When you walk up to a rectangle, it still looks like a square, but when you move back, it starts to look more like a trapezoid.
- A door might seem wider from the side than it does straight on, because of how it fits in your eyes.
- When you watch a car drive away, its shape appears to get smaller and its lines start to converge, that’s the illusion of distance at work.
