SelfGOL - I bet it is very obfuscated.

SelfGOL looks very interesting:

The SelfGOL program can:

self-replicate by printing its own source code,
rewrite other Perl programs to allow them to self-replicate their own source code too,
detect and report the small number of Perl programs that are not rewritable in this way,
transform itself or other Perl programs into cellular automata of arbitrary size and play Conway's "Game of Life",
animate any short text as a cycling marquee banner.

SelfGOL accomplishes these feats in under 1000 bytes of standard Perl, without importing any modules, and without using a single if, unless, while, until, for, foreach, goto, next, last, redo, map, or grep.

Has any one been on this course?

I've seen Damian give shorter versions of the SelfGOL presentation at a couple of conferences over the last few years. It's a very scary piece of code :) -- <http://www.dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]

Some more information on SelfGOL (including the source) can be found here It also gets a mention in the Panther book (2nd Edition, Chapter 10). Oddly enough, in the section on obfuscation :D Cheers, Darren :)	[reply]
