Also in color:

    docker run --rm -it msoap/ascii-art sh -c 'ls /usr/local/share/endoh1/'
    docker run --rm -it msoap/ascii-art sh -c 'endoh1_color < /usr/local/share/endoh1/tanada.txt'
    docker run --rm -it msoap/ascii-art sh -c 'endoh1_color < /usr/local/share/endoh1/column.txt'

  wget http://www.ioccc.org/2012/endoh1/endoh1_color.c
  cc -DG=1 -DP=4 -DV=8 endoh1_color.c -lm # Parameters — factors of gravity, pressure & viscosity
  ./a.out < endoh1_color.c

Got it working on Mac with this, thanks!

What's amazing to me is that the source code is actually formatted to say "Fluid color" which is why piping the source into the generated binary (as in the 2nd command above) generates that image. Incredible.

The video also has color if you watch all of it. And a nice bit of water music.

Whoah check out quine-relay on his github. 128 language quine including a massive apt-get command to install all the compilers/interpreters first. heh.

The YouTube recommendation algorithm strikes again :)

(As of this comment, the video nkoren linked of this project has 650k views vs. ~1k to 4k for the rest of Yusuke Endoh's videos)

We can barely take a step in the modern world without something being quantized.

Why do most people not seem to find it interesting unless it's applied to physics or ascii text (or computer graphics to generalize the parlance a bit)?

I admit I love it though, just not sure why.

Im fascinated by Yusuke Endohs work. I followed him ever since someone posted a random quine of his on here.

Reninds me of the water in one of the early King's Quest[1] games.

I wonder if this could be Turing complete?

You can build fluid-based logic gates[1], so I think it should be possible to make a Turing machine (with the usual caveat that you'll most likely need such a large grid that actually simulating it is impractical)

Oh fluidics. Darn. I was hoping for some Boolean logic encoded directly in Navier-Stokes or something, e.g. some bath of water that had Turing complete flow patterns in some way. Though I guess that would actuallly solve the Millennium Prize problem...
