Battlesnake’s Brad Van Vugt:

This past spring on Coding Badly, Joe and I, for whatever reason, challenged ourselves to build a camera-controlled Battlesnake. The result was “Facesnake” – a Battlesnake controlled in real-time using your face and webcam. This post outlines how we built it using Replit and tracking.js :-)
