Could you build this?
Partial While an app shell is simple, tapping into undocumented private macOS IOKit hinge sensor APIs and writing a high-performance 120 FPS custom Metal shader that captures the screen live requires low-level systems and graphics programming.
What it would actually take: The app is written in Swift/Objective-C accessing private IOKit/IOHIDEvent interfaces to poll the MacBook lid angle sensor at 120Hz. The visual rendering requires Apple's ScreenCaptureKit paired with a custom Apple Metal compute and render pipeline to simulate physically based frosted glass refraction, perspective, and blur without UI latency or excessive battery drain.
