Lightsaber Escape is a Chrome Experiment that Google made in conjunction with Lucasfilm and Star Wars visual-effects studio Industrial Light & Magic. It uses WebGL for the 3D graphics, plus WebRTC and WebSocket for the real-time communication between your phone and desktop. It may be a Chrome Experiment, but this one works in other browsers, too.

If Chrome and Safari can get along, maybe there's hope for the First Order and the Resistance, after all.
