Shatter Walls
No gap to find — the wall is made of individual brick segments, and every hit chips
one down. Break a segment enough times and it shatters into voxels for good, opening
a permanent hole right where it stood.

How it works: the ring boundary is divided into evenly-spaced brick
segments, each with its own hit-point counter. When a ball collides with a segment
that still has hit points left, it bounces off exactly like a solid wall (same
elastic reflection as the other demos) and that segment's hit points drop by one,
flashing brighter with each hit. Once a segment reaches zero it shatters into voxels
and disappears permanently — the ball can now fly straight through that gap forever.
There's no timing or aiming involved, just attrition: keep bouncing and every wall
eventually gets chipped down to nothing. Once every segment on the current wall is
gone, a fresh wall builds one ring further out and the cycle repeats.
