Getting Close with the Web
summary
Compares actual transports by demoing WebRTC vs WebSocket latency and showing how long polling chunks as server delay increases, claims peer-to-peer cuts round‑trip time. Builds a room‑wide jumbotron from phones that share display, audio and timing, implements position sync using angle symmetry and uses AR codes via getUserMedia to refine proximity. Uses tween.js, references JS Aro and Patatap, admits demos sometimes fail but most features work.
