Drag-to-Tilt Slider

Why This Control Is Terrible

Instead of dragging a normal slider handle, users must grab the edges of the container and physically tilt it like a phone game. A ball inside rolls around based on the tilt angle. The value is whatever the ball happens to roll over. The ball has realistic physics and can get stuck in corners or roll back and forth. There's no direct manipulation - you're at the mercy of virtual gravity.
