Cool idea, however I could not get it to work with Chrome on a laptop as a host (with the moving qr codes) and a S5 phone (join) also running Chrome pointing at the laptop (it could see the qr codes on the transparent video). It didn't connect.

I'm sorry to hear you could not get it to work, this means I have to improve the flow. I tested this using Chrome and both Android and iOS devices (chrome and safari). The catch is that you gotta point the series of qr codes towards the center of the camera.
