@tml@urbanists.social @wonderofscience@mastodon.social Right-click the video → Show controls → click ⋮ on the right side → Playback speed → 0.25, and it should become fairly obvious how it's done (edges and centre of the lines fade at different speeds, which creates the illusion; arrows show the direction in which the edge fading is happening).

@jernej__s@infosec.exchange @tml@urbanists.social @wonderofscience@mastodon.social what's wild to me is that if you cover the arrows, you can still tell directionality based on the flash pattern. Way cool.
