The burger in the top-right opens it: the menu wipes down, links cascade in one by one, and hovering each link crossfades a preview image on the right.
It's this page's real menu — try it now.
Watch the top bar: at the very top of the page it's tall and transparent; the moment you scroll, it compresses and gains a frosted blur.

The soft pill behind the nav links has been following you this whole time — it glides to whichever section you're reading. It's on "Nav" right now.

These are the effects you hearted — from every wing.
