ASCII art holds a place near and dear to our hearts. If you were fortunate enough to get started in computers before there was such a thing as a graphical user interface (GUI) then you remember tolling for hours to make clever use of the ASCII characters to make on screen graphics appear as realistic as possible.
Although this animated ASCII fluid dynamics simulator dates back to 2012, it’s just too cool not to share. It’s the product of the International Obfuscated C Code Contest (IOCCC). A contest held each year where the goal is to write the most confusing C code that you can – making use of loopholes and ambiguity in the C programming language to obfuscate(hide) the purpose of the program. Basically, doing everything you’re taught not to do in school. You can take a look at the source code here.
We’re sure the programmer [Yusuke Endoh] would be the first to admit, that there is no practical use for such a low resolution simulator, but we give it an A+ in the retro cool department anyways. (Not to mention, the source code is way too confusing to even comment on) Take a look at the animated ASCII graphics in the video after the break.

The International Obfuscated C Contest – the contest to create the most useful, useless, or unique program in absolutely unreadable C code – has just posted the winners of the 2013 contest.
Of the entries of note, a few really stand out. The pic at the top of this post, for instance, comes courtesy of this submission. It’s an iterative ray tracer stuck inside an infinite loop that, when left running overnight, is able to produce amazing renders.
An IOCCC contest wouldn’t be complete without some ASCII art C code, and this entry fits the bill. It’s a Tetris painting tool that creates images made out of tetronomoes. Each image is built up one line at a time from the bottom up, using Tetris’ lack of physics to create a picture out of un-cleared lines.
One of the most impressive entries for this (last?) year’s contest is a tiny 8086 PC emulator/virtual machine written in only 4043 bytes of code. It’s a fully functional 80s-era PC emulator that can run vintage copies of AutoCAD, Windows, Lotus 1-2-3, and SimCity.
All the submissions are awesome, but like any IOCCC contest, there aren’t actually any winners. Or they’re all winners. The Obfuscated rules aren’t very clear in that regard.
