Decimen Optical Transfer - Transferring files between devices with QR fountain codes

by BashAlarmist

Send a file between two devices using nothing but a screen and a camera. One page displays the file as an endless stream of animated QR codes; another device points its camera at it and reconstructs the file. No network path between the devices, no app, no pairing, no permissions beyond the camera. The payload travels as light. Built by BashAlarmist.
