> Other than aesthetics, what are the advantages of the point cloud? Higher bandwidth? Higher information density, in that it can pass ad-hoc wifi network info and cryptographic keys. The animated "QR code" also contains a unique code in each frame that is then sent back during the pairing process. This allows them to measure the round trip time from display to camera to wifi back to the original device, preventing relay and replay attacks. (This is based on my attempting to reverse engineer watch pairing for a few days)
