Port from the original Perl version.

Where is the original Perl version?

Here is one:

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 :)

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.
