LED AppBar pins a scrolling LED dot-matrix ticker to the very top edge of your Windows desktop — not as a floating window, but as a real Windows AppBar via SHAppBarMessage. That means maximized windows respect the bar's space instead of overlapping it, exactly like the taskbar. Point it at any URL: RSS news, clocks, Twitch chat, scrolling illustrations, whatever renders in a browser. Built with Tauri (Rust + WebView2). Multi-monitor support, auto-hides on fullscreen, ~4 MB installer.
