Impossible Occlusion: Does the bar pass behind or in front of the pillars?

Occlusion Ambiguity

Spatial paradox: when Object A is both in front of and behind Object B.

🧐 What do you see?

A horizontal bar moves past vertical pillars.High Intensity: The bar appears to passbehind the middle pillar butin front of the side pillars—a geometry that shouldn't exist!

🧠 Why this works

This is an Impossible Figure derivative. Our brain prefers to see objects as solid and continuous. When we useLocal Occlusion Cues (like Z-indexing changes) that contradict each other, the brain struggles to build a coherent 3D model.

🧪 Try variations

Lower the Intensity. The illusion resets to normal 3D logic, letting you see the difference between "possible" and "impossible" depth layering.
