From the README

Every letter on a web page becomes a creature with a body and mass — and flies off in a flock, like starlings.

▶ Live demo · 🔖 Install the bookmarklet · All versions

The demo and the bookmarklet speak English; a Russian version is available too: demo · bookmarklet.

Murmuration — letters fly as a flock, like starlings. Horde — letters run towards the cursor, like a crowd of zombies. Rest — letters stay in place. Sweep the cursor over them and they take off, then settle back.
