Drag in any direction to rotate. Scroll or pinch to zoom. When idle, the cap smoothly returns to a slightly elevated angle and spins horizontally. Click or press Enter to expand. Arrow keys rotate, plus and minus zoom, Home resets the view, and Space pauses or resumes spinning when expanded. Quickly tap anywhere, including on the cap, or press Enter or Escape to shrink the expanded view. Dragging and long presses do not shrink it.
