I'm not sure when I'd use this, but its a neat concept

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.

there's a bunch of open source (and abandoned) repos on GitHub that do this using fountain codes, fascinating stuff but not all that good, they have huge limits on the transfer rate. I recalling seeing some that use JAB codes which cram more data into each code using colours, not sure how much better they'd be than this though.

I should probably mention that a fountain code isn't a barcode like a QR or JAB code, they're a way to do error correction which can be applied to sequences of barcodes
