Show HN: SpinWin – A macOS menu bar app to visually rotate or spin any window

SpinWin is a macOS menu bar app that visually rotates or spins any window by hiding the original window off-screen and displaying a rotated overlay of its contents using screen capture technology. Since macOS lacks a public API for window rotation, the app uses the Accessibility API to hide windows and ScreenCaptureKit to continuously capture and redraw them at any angle on a transparent overlay. The tool supports preset angles, continuous spinning, and free rotation, though the overlay is non-interactive and doesn't forward clicks or keystrokes to the underlying window.
