I built a Flappy Bird clone that you control by opening and closing your MacBook lid. It uses the hinge lid angle sensor recently discovered by @samhenrigold!

This has no monetization, no ads, and is all ran locally. This is a throwaway account as I'm not sure I ever want this abomination attached to me professionally.

There are two game modes: "Easy Mode" where the bird follows your lid position directly, and "Flappy Mode" where you flap the lid to jump (with proportional jump heights based on how much you move the hinge).
