You might have heard of the The International Obfuscated C Code Contest, which has run since 1984 and challenges programmers to come up with novel programs whose source code is obfuscuated. The contest has been on and off over the years, but the results for the 28th contest have finally come in, and one of the winning entries should be of interest to this community - a Z-machine interpreter!
It just supports version 3 Z-machine files, but it’s pretty impressive for how small and, well, obfuscated its source code is.
