OpenBendy, the MacBook Hinge Trick

Field notes

The utility maps a MacBook’s physical hinge angle to a live desktop transformation, with Silk, Shade, and Frost modes plus controls for perspective, blur, shadow, and the clearing angle. It runs from the menu bar and uses Esc as an immediate escape hatch. The page says screen frames remain in memory, with no uploads, saved recordings, or account, but the downloadable build is still signed for development and not notarized.
