Skywall

4K underwater wallpapers for Mac.

Kelp forests, dolphin pods, jellyfish and reef sharks, filmed below the surface. The slowest films in the set.

The most varied set.

Jellyfish in Palau and in Alaskan water, waves breaking over reef in Tahiti, gray reef sharks, bumphead parrotfish, a humpback whale, barracuda schooling, seals, sea stars, dolphins off Costa Rica and a kelp forest in California.

Why they read differently on a desktop.

Underwater footage moves more slowly than anything shot from the air, and it holds a single colour for minutes at a time. On a desk that matters: the blue field behind your windows does not compete with them the way a city street does. If a live wallpaper has ever felt distracting, start here.

Where 4K shows.

Kelp fronds, a jellyfish bell and the pattern on a reef are fine detail, and any smaller re-encode loses them. Skywall plays the original file untouched, so what reaches your display is what the camera recorded.
