Could you build this?
No Reading MacBook lid angle hardware sensor values requires reverse-engineering private IOKit APIs or Apple Silicon SMC/accelerometer hardware sensors in native Swift/C.
What it would actually take: A native macOS Swift app that interfaces with undocumented IOHID/IOKit or Apple Silicon SMC sensor registries (such as the lid angle sensor present in newer MacBooks). It requires low-level Darwin systems programming and reverse-engineering Apple hardware sensor identifiers, along with real-time audio pitch/playback modulation based on angular velocity.
