Radiation-hardened Quine (2014)
This comes from the same dev known for the 128-language quine relay, where each of the 128 languages prints a program in the next one, looping all the way to the original one. In alphabetical order and as ASCII art, no less.<p><a href="https://github.com/mame/quine-relay">https://github.com/mame/quine-relay</a>
