Decimen is an open-source web app that moves files between devices through an animated QR stream, requiring no direct network connection, pairing, account, or native app.

Visible light data transfer isn’t new either. The Timex Datalink watches were using flashing coloured patterns on a PC monitor to send data to them in the 90s.
