Swarm Clock

Particles swarm into the time, regroup when it changes and scatter from your pointer.

About the Swarm Clock

Swarm builds the time from more than a thousand tiny particles, a pool of them for every character. Each particle is pulled onto a point of its digit and shivers there; when a digit changes, its pool is knocked loose and swarms across to form the new one while the rest hold their shape. Pale lavender particles float on near-black, with the seconds in pink.

Move your mouse or finger over it and the particles flee, then stream back to their digits when you move away; a vertical swipe still scrolls the page. They rest in place when your device asks for reduced motion. It reads 12-hour or 24-hour time, fills the whole screen in its own colours and is one of the fifteen digital faces of Clock with Seconds.
