Given that Christmas is coming up, and it never seems to get traction here on HN, I'll take the opportunity to link to another of his quines here. It's one of my favourite pieces of code ever, a christmas-themed animation which doubles as a quine:
So I was sad to see it only available in Japanese. But then, I was happy to have found something written, potentially for the joy of it, not necessarily on the main stage to maximize internet reach.
This is absolutely mind boggling to me. I've written a normal quine before and that was a fun challenge, but this is just so incredible I have absolutely no idea how it's even remotely possible.
Not applicable specifically to Quine Relay, but the author gave a few interesting talks in English over the years at RubyConf where he discusses some of the obfuscated code techniques he uses:
I have no idea how this is implemented, but for regular quines (i.e. just a program that outputs its own source code) reading the source file is obviously not allowed. Plus there's isn't really a "first language" since the whole thing is a loop anyway.
Ikr? I saw him present this at a conference, you could almost hear the audience collectively recalibrating their self-image in light of this new data point.

Edit: I have to re-iterate, he is truly a genius. It's worth spending time going through his other videos too.
