Starling 0.5 Adds a 3D Desktop You Can Walk Through

A few months ago Phoronix introduced Starling — a new Linux desktop with its own Wayland compositor, written in the Swift programming language and produced in large part with AI via Claude Code. Version 0.5 is out now, and its headline feature is an optional 3D desktop mode.

A walkable waterfront city

The familiar 2D desktop doesn't go away — the 3D view sits alongside it and switches on from the control panel via the "3D Desktop" option. As the developers describe it, you find yourself in a walkable three-dimensional waterfront city, complete with moving boats, traffic and drifting clouds, a clock tower, sunset lighting, and window chrome in cream, bronze and sage.

The windows are still real

For all the scenery, Chrome, the video player, Files, the terminal and the other apps remain actual windows. You switch between them with Alt + Tab or pull a live preview forward from the rail. Double-clicking a window's outer title bar centers the camera on it, and popups follow their parent window within the scene.

Each display gets its own scene and camera: walking, turning or pointer-driven parallax on one monitor leaves the other's view untouched. Scene rendering shares a backend while keeping each output's camera and render target independent.

The Phoronix author notes the whole thing recalls Sun Microsystems' Project Looking Glass, covered on the site twenty years ago — a striking throwback.

Beyond the 3D city, Starling 0.5 now also runs on Windows through WSL2 with Ubuntu 26.04 using the RDP display mode. This release, the developers say, was worked on by the Claude Fable 5.1 model. Further details are on GitHub.
