Hey thanks a lot, that should be the actual link behind the submission. Very interesting technique that boils down to encode a url with a ton of carefully shaped random numbers hidden in the fragment to generate the actual art.
That's the example url from the linked blog introducing this technique http://swtch.com/pjw/#123456789...
Source Code (Go) is here: https://github.com/rsc/qr/tree/master/qart

Messing with that demo page, it seems to manipulate the URL you put in there too adding some numbers after an anchor tag (#) at the end, rather than just error correction.
Interesting I was wondering about this, if you control the domain and web server technically you could even make a full path of arbitrary data that then redirects to the real target.
Made me wonder how easy it is to embed QR codes inside everyday images/objects without them being visible until you scan the object.
Does this mean you could make a gif which is a valid QR code playing Bad Apple?
A series of QR codes that each link to the next frame of bad apple is the logical conclusion to me
