Iron-filing particle effect — magnetic field motion that reacts to a moving anchor. Hypnotic abstract loop for hero backgrounds.

Under the hood the animation uses scale animation, translation motion, canvas drawing, wave motion, character-by-character reveal. Every effect is defined in plain React code, so you can tweak timing, colors, and copy without ever touching a timeline or keyframe editor.

Use it as a motion template in 9:16. Remix in Motn to edit the prompt, regenerate with AI, swap fonts and colors, then export as React, standalone HTML, or a 60fps MP4.
