Dev builds 3D bike ride simulating relativity with light slowed to 20m/s, using Claude

- A developer built a 3D game-like simulation of Einstein's special relativity using Claude Opus 5.5: riding a bike through a city where light crawls at 20m/s.
- As you approach light speed, the street wraps into a glowing tunnel, and invisible heat from the walls shifts into visible light via the Doppler effect.
- The 'slow light' concept traces to George Gamow's 1939 book Mr Tompkins in Wonderland, whose drawings showed squashed cyclists — modern physics says you'd actually see the tunnel instead.
