    ./dhyang

Try:

    ./try.sh

Judges’ remarks:

A beautiful combination of solving several different problems, but mostly, the single most impressive layout we’ve ever seen. Many programs have one interesting layout; this one has four.

It may be informative to run the code through a “beautifier”, to study it, but the layout itself is where most of the interest lies.

Author’s remarks:

This one is dedicated to Saitou Hajime fans ^_^x

Instead of making one self reproducing program, what I made was a program that generates a set of mutually reproducing programs, all of them with cool layout!

For your enjoyment:

1. Compile dhyang.c.
2. Run ./dhyang and redirect output to another .c file.
3. Compile that file.
4. Repeat steps 2 and 3 until eventually the output cycles.

To interpret the output: the dhyang.c is an image of Saitou Hajime, which eventually generates three sources files that are images of “aku soku zan” (sin swift slay), Saitou’s motto ;)

For best viewing, set tab spaces to 8 characters, and set your terminal fonts to as close to square as possible. I hate to do this but you know, size…

dhyang.c and all its output compiles with gcc if your OS uses ASCII character set. No file is included and all functions assume default int return type (a source of compile warnings).

Primary files

• dhyang.c - entry source code
• Makefile - entry Makefile
• dhyang.orig.c - original source code
• try.sh - script to try entry

Secondary files

• 2000_dhyang.tar.bz2 - download entry tarball
• README.md - markdown source for this web page
• .entry.json - entry summary and manifest in JSON
• .gitignore - list of files that should not be committed under git
• .path - directory path from top level directory
• index.html - this web page
