This Hacker News post showcases an interactive web simulation where the speed of light is set to 5 km/h, allowing users to explore relativistic effects at walking speed. The demo illustrates phenomena such as length contraction, time dilation, Doppler shift, and Terrell rotation as velocity increases toward the light-speed limit.
