Did you know your MacBook has a sensor that knows the exact angle of the screen hinge?

It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

@T_X @samhenrigold Nice. That could even be a theremin where one can hold a tone. How would we do volume ;) ?

@kellertuer @samhenrigold two MacBooks maybe :D? I'm wondering if that could be done via #MIDI over #Ethernet or MIDI over #RTP (or does MIDI over X expect both the tone and volume to come from the same source? is MIDI even suitable for an analog pitch?)
