Got tired of every live wallpaper app installing a browser engine to loop an mp4 behind my icons. Installer, launcher, background service, bundled Chromium, five processes, all to play a video file.

This composes straight into the Windows desktop composition tree instead of sitting as an overlay window, so the shell does the compositing. Video or image per monitor, seamless looping, optional clock widget. Stops decoding entirely when a fullscreen app takes focus. 0% CPU at rest, 0.9% on a 4K loop, one process, 7.5 MB, no account, no telemetry.

Honest about the limits: needs the .NET 10 desktop runtime, Windows 10 1809+ or 11 only, and multi-monitor plus mixed-DPI are still rough. It's v0.1.0.
