Mac Duo

Mac Duo is a native Swift and Metal macOS app that makes desktop effects follow the position of a MacBook lid. It provides six transitions—Duo, Ghost, Roll, Shutter, Flex, and Iris—that animate the desktop around the hinge, including panel sliding, display curling, bowing, or iris-like closure. The app includes live preview, floating controls, menu-bar access, pause controls, and an option to clear the screen after the lid remains still. It runs locally without third-party runtime dependencies, accounts, analytics, or screen-content uploads; screen frames remain in memory when Screen Recording permission is enabled. It supports macOS 13 Ventura or newer on compatible Apple-silicon MacBooks, with an Intel preview for the 2019 16-inch MacBook Pro, and is distributed under the MIT license.

Lid Plane is a macOS menu bar app that creates a MacBook lid-folding illusion using the laptop's hinge-angle sensor. It captures the built-in display with ScreenCaptureKit, reshapes the captured image with a Metal shader as the lid moves, and blends increasingly blurred copies using Metal Performance Shaders; the blur increases with lid movement and is stronger near the top of the display. The app can use a selected activation angle or a movement-based mode that anchors the effect after motion stops, while the underlying applications remain clickable and retain keyboard focus. It requires macOS 13 or newer, an Apple silicon MacBook, a supported lid-angle sensor, and Screen Recording permission. The effect applies only to the built-in display, pauses during closed-lid or unsupported-display states, and keeps captured frames in memory without saving or transmitting them. It is built with Swift, ScreenCaptureKit, IOKit, and Metal, and is distributed as a downloadable app for Apple silicon. The repository is licensed under GPLv3-or-later from version 0.3.2 onward; version 0.3.1 and earlier remain MIT-licensed.

A browser-based Three.js study of foldable-screen transitions that recreates an iPhone Duo fold animation with projected screen UI, progressive blur, and custom image uploads. Only the cover half rotates while the rear-camera half remains fixed; screen content uses a front-view projection, and blur and darkening follow image coordinates during the fold. It provides Wallpaper, Launcher, and Custom modes, with orbit controls, zooming, a fold slider, and a play button. The application is static HTML, CSS, and JavaScript with Three.js bundled locally, and can be deployed to Vercel or another static host after preparing the Apple reference assets. The original application code is MIT-licensed; Apple models and imagery are excluded from that license and remain subject to Apple's terms.

MacTap is a macOS menu-bar app that turns one, two, or three knocks on a compatible MacBook chassis or the desk beneath it into keyboard shortcuts and other mapped actions. It supports left- and right-edge layouts, configurable sensitivity and actions, presets such as Daily, Coding, Capture, Media, and Focus, and per-application overrides. Tap classification runs on-device, with gesture mappings stored locally and nothing uploaded. It requires macOS 14.6 or later and a MacBook whose motion sensor is exposed as an SPU HID device, including M2-and-later models and M1 Pro, Max, or Ultra systems; some M1 models, including the original M1 Air, are unsupported. The app requires Accessibility permission for actions to send shortcuts, is distributed as a signed and notarized macOS app, and is licensed under the MIT license.

Cyclop is a native macOS SwiftUI/AppKit utility that turns the MacBook notch into a hover-activated panel. It provides media controls for players and browser tabs visible to macOS, a drag-and-drop file shelf, clipboard history, reusable text snippets, calendar entries with meeting join buttons, offline English–Russian translation using macOS facilities, a teleprompter, and scratch notes. The panel unfolds when the pointer reaches the notch and collapses when it leaves; it can also open automatically during file dragging and remain open while a teleprompter script scrolls. The project is distributed as free, open-source software with no external dependencies, requires macOS 15 or newer, and needs one permission granted during first launch.
