HN comment orderFabrice Bellard (the wizard behind FFmpeg, QEMU, etc.) has his own entry, which I find amazing: a ~4 kB program that outputs a ~50 kB image (of Lena), in addition to being able to decompress other images. His entry's hint page: http://www.ioccc.org/2018/bellard/hint.html
Tromp's entry is amazing. Source: http://www.ioccc.org/2012/tromp/tromp.c Spoiler: http://www.ioccc.org/2012/tromp/hint.html It's based on a minimal implementation of Binary Lambda Calculus: http://en.wikipedia.org/wiki/Binary_lambda_calculus
