Show HN: Photo Realistic QR-Codes
Slightly OT, but when migrating data between iPhones, the old iPhone displays an animated point cloud that appears to function like a QR code. You scan it with the new phone, and your data starts to migrate locally through Bluetooth.<p>Other than aesthetics, what are the advantages of the point cloud? Higher bandwidth?<p>Also, if you were to transfer 100s of megabytes of data from device A to B, using A's display and B's camera, what tech would you look into?
