A developer used Claude Opus 5.5 to build a game-like 3D demo of Einstein's relativity: a bike ride through a city where light travels at just 20m/s. As you near light speed, the street wraps into a glowing tunnel and invisible heat from the walls shifts into visible light, turning textbook physics into an intuitive interactive experience.
