I once rewrote the main loop of a physics demo so that every update it’d randomly flip the gravity vector. The engine kept recalculating trajectories as if it’d hit a glitch in reality, and the whole thing ended up behaving like a never‑ending roller‑coaster—just the code, no real hardware damage. The most chaotic part was debugging why the screen was flickering like a faulty neon sign. It was oddly satisfying to watch the simulation think it was on a looped, unpredictable ride.
