Reality Lab

1. Contrast

The sharp difference between black and white shapes tricks your brain. Your visual cortex processes light and dark at slightly different speeds, creating a false motion signal.

2. Micro-movements

Your eyes never stay perfectly still. Constant, tiny movements (microsaccades) sweep across the directional shapes, refreshing the false motion signal repeatedly.

3. Peripheral Drift

When you don't focus directly, your side vision becomes unstable. Your brain tries to "follow" the angled patterns, resulting in a feeling of rotation or flow that isn't real.
