DECIMEN Fountain QR File Transfer

by Gifamoss: AI

One night with Claude Code and this dev accidentally built an AirDrop killer that doesn't use wi-fi or bluetooth at all. the trick is wild: one phone blasts hundreds of QR codes per second, so fast your eye just sees a static square, while the other phone's camera grabs every frame and stitches them back into the original file. he clocked 365 KB in 2.6 seconds, that's 140 KB/s, straight through air and glass. and he wasn't even aiming for this. the plan was a simple web-based MP3 player with no ads. instead he ended up inventing a data channel that used to only exist inside research labs. the screen overlay says 'DECIMEN - Fountain QR File Transfer' and '60 FPS - 2953 bytes per frame', basically a whole R&D lab in one red-cased phone. it's the kind of shift that sounds like hype until you see the numbers: one developer + AI = an entire R&D lab. stuff that once needed 10 engineers and half a year now ships overnight by a single person with a laptop
