iPhone Duo

Mac Duo is a free macOS menu-bar app that recreates the iPhone Duo visual effect on compatible MacBooks. As the lid closes, it uses the built-in lid-angle sensor and ScreenCaptureKit to capture and render the live screen, while Metal applies perspective, blur, and dimming. The perspective is adjustable, and the app supports English and Simplified Chinese. It requires macOS 14 or later, a compatible built-in lid-angle sensor, and Screen Recording permission. Prebuilt downloads are provided for Apple Silicon and Intel Macs; the project can also be built with Xcode using Swift 6.0 or later. The effect applies only to the built-in display, stops when macOS sleeps, and passes clicks through to the applications underneath. The code is licensed under Apache License 2.0.

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.

A framework-free WebGL2 package for rendering Apple-inspired translucent glass surfaces for folders, rectangles, pills, and circles. Its renderer models screen-space refraction using a squircle signed-distance-field thickness field, Snell refraction with a meniscus rim, variable-blur scattering, Fresnel reflection, chromatic dispersion, edge highlights, contact shadows, hit testing, and live backdrops. It provides the original frosted V1 renderer and a separate clear optical V2 renderer, each with its own material contract; both can be used together. The package is distributed through npm, requires WebGL2, accepts CSS-pixel element coordinates, and can load image backdrops.

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.

Viscose is a portfolio carousel rendered as a single full-screen WebGL fragment shader rather than a grid of DOM elements. Project cards travel around a mostly off-screen ring that can be turned by scrolling, dragging, swiping, or clicking; momentum carries the ring and it snaps the nearest card to the front. Signed distance fields make neighboring cards melt together as they approach and form thin, sagging threads as they separate, while pointer interaction softens the field, shifts nearby cards, and creates connecting effects. The same shader pass renders the threads, the refracting glass-like edges at the top and bottom of the viewport, and the cursor tag. On touch devices, swiping turns the ring and press-and-hold triggers the hover effects. The project includes a development-only lil-gui panel with roughly 136 live parameters and is built with Next.js, React, Three.js, GSAP, and Tailwind CSS; it requires Node.js 20 or newer to run locally.
