You can pull blocks from a brick ring or fire a cannonball into it. The rigid-body simulation runs on your GPU in the browser.
The ring is built from thousands of pastel-colored bricks. A cannonball breaks through its wall, sending bricks into the air and leaving a pile on the floor.
How to explore
- Drag a block to pull it, or press Space to fire a cannonball.
- Drag away from the blocks to orbit the view, and scroll to zoom.
- Select “Replay the smash” to watch the collision again, or press R to restart the scene.
