This isn't Earth's ocean.
Ocean Clock started from a simple idea: what if your screensaver felt less like a wallpaper and more like a place? Every wave, ripple, and reflection is generated in real time by a shader running on your Apple TV — there's no looping video underneath.
Watch long enough and the sky will drift from blue hour into full night, moonrise, dawn, and back again. And every now and then, something enormous moves just beneath the surface. Nothing dramatic — just enough to make you stop scrolling your phone and actually look at the TV.
