Could you build this?

Partial Accessing the MacBook's private IOKit/HID lid-angle sensor APIs and rendering full-desktop Metal shader distortion effects requires low-level macOS system programming.

What it would actually take: The app needs a native macOS Swift/Objective-C wrapper that interacts with private IOKit HID lid sensor events (AppleSilicon/Intel HID reports). The desktop display must be captured via ScreenCaptureKit and routed through a custom Metal rendering pipeline executing 3D deformation shaders (folding, black hole warping) mapped to the real-time angle float. Deep knowledge of low-level macOS graphics and undocumented hardware sensors is essential.
