Cursor Trail

A shape or label trails the pointer with a spring or eased delay.

Add a "Cursor Follower" (also called a following pointer or smooth cursor) to [where].
A small round marker should trail the pointer with a soft, eased delay and glide to a stop right where the pointer rests, without bouncing.
Keep the real pointer visible, never let the marker block clicks, and leave it out on touch devices.

The default arrow is replaced by a styled dot or ring that changes over interactive elements.

Add a "Custom Cursor" (also called an animated cursor or cursor replacement) to [where].
Replace the default arrow with a small dot that tracks the pointer exactly and a ring that follows a little behind, and let the ring grow smoothly while it is over links and buttons.
Keep the normal cursor on touch devices and in text fields, and never let the custom cursor block clicks.

The element is pulled toward the pointer as it comes close, then snaps back when it leaves.

Add a "Magnetic Button" effect (also called a magnetic target or magnetic hover) to [where].
As the pointer comes close, the button should be pulled a little toward it with its label moving slightly further, and when the pointer leaves it should spring back to its place with a small bounce.
Keep the surrounding layout from shifting, and turn the pull off on touch devices and for users who prefer reduced motion.

A field of small lines rotates to point at the pointer, like iron filings around a magnet.

Add a "Magnetic Filings" effect to [where].
A grid of short lines should each turn to point straight at the pointer right away, like iron filings around a magnet, and all face the center when there is no pointer.
Keep it a decorative background that never blocks clicks, and leave the lines still for users who prefer reduced motion.
