Skywall
Kelp Dark, an Aerial film shown full frame

What the camera passes

  1. Drifting through a kelp forest near Cape Peninsula, South Africa

How to set Kelp Dark as your wallpaper

  1. Install Skywall and open it from the menu bar.
  2. Find Kelp Dark in Underwater — the app groups films exactly as macOS does.
  3. Click the card. Skywall fetches the film from the source macOS points at, into the folder it already uses.
  4. It becomes the wallpaper on every display, and the screen saver when the Mac goes idle.

Nothing is copied to our servers, and nothing is left behind if you remove the app — the film stays in the system’s own Aerials folder.
