A fast, single-file console application that generates per-output wallpapers and assigns them directly to every Windows display. Inspired by Sysinternals BgInfo, built for creative professionals: AV technicians, video engineers, and real-time graphics specialists.
Highlights:
One PNG per display, sized to its native resolution and anchored to its desktop position.
Format strings with ${tokens} for dynamic substitution and per-line size and color cycling.
Slices to split any output into multiple regions, each with different settings.
Short-lived and idempotent: runs until done then exits, skipping re-rendering when config, version, and hardware fingerprint all match.
TOML-first configuration with CLI overrides, auto-seeding a config from defaults on first run.
Portable single-file executable with no runtime dependencies, built for speed via NativeAOT compilation.
