In Relativity Park the speed of light is set to 5 km/h, a brisk walk. Accelerate with the arrow keys or WASD and the view ahead squeezes together and turns blue while the scene behind stretches and reddens, and two on-screen clocks, your watch and the world clock, drift apart as you go. Lamp posts flash once per second of world time, and the Ferris wheel, carousel and a shuttle move at 75 percent of light speed, which makes length contraction and Terrell rotation visible on their own. Light-travel delay, aberration and contraction, Doppler color and relativistic beaming each have a key to switch them off, so you can see which effect causes what. Dmitry Brant built it and published the source code.
