Of course, one can also write perfectly readable code, and then run it through a code obfuscator to convert it to something that even SETI couldn't distinguish from background noise. (But which still compiles without error and generates a working executable)
(There are actually code-obfuscation contests, where people can compete to generate the hardest-to-read code imaginable. For example, http://www.ioccc.org/main.html , the International Obfuscated C Code Contest)
