A crazy Ruby quine: a spinning globe.

Equally impressive: http://d.hatena.ne.jp/ku-ma-me/20090916

A Ruby -> Python -> Perl -> Lua -> OCaml -> Haskell -> C -> Java -> Brainfuck -> Whitespace -> Unlambda -> Ruby quine!

[chrisaycock → vito]

A polyglot quine! There should be special obfuscated contest just for that.

1. Copy one of the above as a.rb.

2. Run

while true; do clear; ruby a.rb | tee b.rb; sleep 1; mv -f b.rb a.rb; done

[DougBTX → SlyShy]

Smoothing the animation:

   while true; do clear; ruby a.rb 3 | tee b.rb; sleep 0.1; mv -f b.rb a.rb; done

That is pretty cool, but the ultimate work of this type that I've seen is this mandelbrot fly-through in perl:

Seriously -- try it.

[orangecat → roadnottaken]

Awesome. Works perfectly on OS X.

[jpadvo]

Does anyone know what kind of process was used to create this?

[softbuilder → jpadvo]

Port from the original Perl version.

[itsnotvalid → softbuilder]

Where is the original Perl version?

[roadnottaken → itsnotvalid]

Here is one:

[riffraff → roadnottaken]

I don't think that's the same thing: the perl code is a spinning world visualization, the ruby code is code producing other code that in the end produces the original one, where the different programs _also_ are visualization of the world, which is a tad cooler :)

[JonnieCache → jpadvo]

With this kind of thing, I think there is a strong case for the idea that you really do need to be born with the right kind of brain.

[rbxbx]

At least the Japanese rubyists remember how to have fun :)

His translated version of the article http://mamememo.blogspot.com/2010/09/qlobe.html (not that there is much to read :-) )

It's really impressive :-)

This is certainly an amazing piece of work.

[donniefitz2]

That is truly impressive.
