More polygen

[Enrico Zini <enrico@enricozini.org>]

Hello,

Today I pushed polygen invocation pipelines a bit further.

Attached is a new polygen grammar that generates polygen invocation
pipelines.

You can use it like this:

   bash -c "`polygen polyscreensaver.grm`"

(before doing it, check the output a bit by just running
  polygen polyscreensaver.grm
and also check the grammar to make sure I didn't put anything nasty in
it :)

And you can have a nice screensaver by increasing the font size of the
terminal and then doing this:

   while true ; do clear; bash -c "`polygen polyscreensaver.grm`"; sleep 10; done

Of course the grammar is a proof of concept and can still be improved by
adding more grammars or filters... but you get the idea.


Ciao,

Enrico
