I'm still waiting for someone to make an app that encodes and decodes large data into multiple QR codes that are displayed in a moving sequence. That would be the best way to transfer files in physical locations.

Apple has something like this for their new iOS device setup. I don’t think it’s to encode larger amounts of data, but for security they have this circle that constantly changes shape (see around 0:50 in this video for a demo: https://youtu.be/iE03ypWD5xs). I don’t know for sure how it works, but my first thought was a constantly changing QR-like code.

I was looking for the snake in the QR code itself (and found it!) before reading the article

Wait, you found a snake? I am confused. Anyways, I too looked for it at first because I expected the game to be visually embedded in the QR code as well. I was a little disappointed that it was not the case. Imagine a game embedded in the QR code that when you load it, either directly is able to reconstruct the QR visual itself, so like some sort of quine https://en.m.wikipedia.org/wiki/Quine_(computing) but with the…

Could be a really fun variation on quinesnake: https://github.com/taylorconor/quinesnake

If you want to see a variation of this concept in the wild, in active use by lots of people, check out PICO-8 cartidges. PICO-8 is a virtual game console. I.e. it's an emulator for an oldschool game console that doesn't exist in reality. It's designed to be easy to code for while maintaining the limits and aesthetics of old game computers PICO-8 games are, of course, distributed on cartridges. However because it's a…

This is the coolest thing in ages. The game's code is steganographically embedded in a PNG image containing the screenshot of the game! Wow

This would look similar to images produced by the Danmere Backer, a device which let you back up your files to a VHS tape.

You should turn this comment into a blog post. Your writing is captivating. You made this ecosystem sound a lot cooler than the web pages you linked to.

a new vector emerges

I was thinking about the same thing! Although the original QR code spec did allow binary payloads[1], smartphones and cameras weren't ubiquitous in mid 90s. But they are now. Transmitting computer virus or malware within the QR code binary payload might just be as easy as pointing your camera lens to the QR code. Since the QR code image is only machine readable not human readable, it would be indistinguishable, neither any digital signature to prevent it from being altered.

Games for the “Redshift” game console in the Zachtronics game Exapunks work the same way. They copied the idea from PICO-8: https://mobile.twitter.com/zachtronics/status/10277956046744...

Cool, so all the 1k demos/intros from Assembly ( https://archive.assembly.org/2019/1k-intro ) could also be distributed via QR code... the 4k intros unfortunately not. Maybe it's time for a new category ;)

Or a QR-code paging system.

(I feel a little evil for even suggesting that)
