- GitHub - mame/radiation-hardened-quine: A robust quine program that works even after any one character is deleted., a Ruby program that prints its source code, even if you change any single character in the original program. Neat.
- AsciiDots, an “esoteric” language based on ASCII Art.
- the ASCII Art archive
- and finally, best of breed, the International Journal of PoC || GTFO polyglot hacker magazine since 2013!
