Made for macOS. Tuned for Apple Silicon. Designed to feel like it belongs.

Your desktop comes alive. And it knows when to disappear.

Atheria turns your Mac into living art: 85 real-time wallpapers and your own video loops that breathe and drift behind everything you do. Each real-time wallpaper is generated live on your GPU with Metal, never a looping clip, never the same frame twice. Built natively in Swift for Apple Silicon, it feels like part of macOS, not a port.

And it respects your machine. The moment another window covers the desktop, rendering stops and the frame rate drops to 0 fps, so your wallpaper never costs you battery or fan noise when you cannot even see it. On low battery or in Low Power Mode, it pauses on its own.

85 LIVING WALLPAPERS
Calm auroras, liquid metal, drifting nebulae, neon light, and dozens more, each generated live on your GPU, not a video file. Tune speed, density, color, and motion until it is yours.

FLAME CREATOR
Grow fractal flames: a small genome of weighted transforms, iterated billions of times on your GPU into living structure. Start from eleven archetypes, roll Chaos to invent brand-new ones, or build from a blank canvas one transform at a time. Mutate step by step and keep every flame you love. Atheria can create more unique flames than there are atoms in the entire observable universe, ~10^300 possibilities!

SHADER CREATOR
Write, compile, and run your own real-time Metal shaders to use as living wallpapers, right inside the app. No Xcode, no build step. Paste GLSL or Shadertoy code and convert it in a click to start from anywhere on the web.

PRIVACY GUARD
Step away and your screen frosts into a clean privacy veil after an idle timeout you set, then melts away the instant you return. No lock screen, no password. Raise it on demand from any app with a single hotkey.

SHARE WHAT YOU MAKE
Every flame and shader you create travels as a short text code or beautiful share card. Drop it in a message or a post, and another Atheria user pastes it to grow the same living art on their own desktop. No uploads, no accounts, no files.

PRESENCE-AWARE DESKTOP
Wallpapers respond in real time to your cursor and your activity, with an intensity slider so the effect stays as calm or as lively as you like.

PLAYLISTS
Mix living wallpapers and video into playlists, shuffle them, and set active hours so your desktop shifts through the day on its own.

PRIVATE BY DESIGN
Atheria runs fully on-device. It collects no data, ships no analytics, and asks for no invasive permissions. No microphone, no screen recording. What is on your Mac stays on your Mac.
