Source Code For 22nd IOCCC Winners Has Been Released

An anonymous reader writes "The source code for the 22nd International Obfuscated C Code Contest winners has finally been released. Many entries exploited bugs in the size check program, making the 2013 entries possibly the most featureful submissions ever."

It's not just the obfuscation...

I find this very impressive, not so much for the obfuscation, but for packing so much functionality into a small bit of code....

Ray tracer + web server + image encoder + clock

[hydrofix]

I found this one [ioccc.org] a pretty mind-blowing entry. When compiled and run, it creates a web server at http://localhost:8224 [localhost], which can be opened in a browser to display a ray-traced 3D scene of steel ball bearings on a checker-pattern surface, arranged to display the current time. Quoting the description:

The program wears many hats (not literally). It is
* a web server
* a PNG encoder
* a ray tracer
* a clock

Unlike the PC emulator entry, it does not require a binary blob and all the code and data fit within the 4 kilobyte limit.
