in reply to Pascal-Sierpinski for golfers

A long time ago, I accidentally wrote this little Sierpinski triangle generator obfu, sier.pl, while playing golf IIRC:

#!/usr/bin/perl -l s--@{[(gE^Ge)=~/[^g^e]/g]}[g^e]x((!!+~~g^e^g^e)<<pop).!gE-ge, s-[^ge^ge]-s,,,,s,@{[(g^';').(e^'?')]},(G^'/').(E^'|')^Ge,ge, print,s,(?<=/[^g^e])[^g^e][^g^e],$&^(G^'/').(E^'|')^gE,ge-ge
Running, for example:
perl sier.pl 5
displays:
/\ /\/\ /\ /\ /\/\/\/\ /\ /\ /\/\ /\/\ /\ /\ /\ /\ /\/\/\/\/\/\/\/\ /\ /\ /\/\ /\/\ /\ /\ /\ /\ /\/\/\/\ /\/\/\/\ /\ /\ /\ /\ /\/\ /\/\ /\/\ /\/\ /\ /\ /\ /\ /\ /\ /\ /\ /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ /\ /\ /\/\ /\/\ /\ /\ /\ /\ /\/\/\/\ /\/\/\/\ /\ /\ /\ /\ /\/\ /\/\ /\/\ /\/\ /\ /\ /\ /\ /\ /\ /\ /\ /\/\/\/\/\/\/\/\ /\/\/\/\/\/\/\/\ /\ /\ /\ /\ /\/\ /\/\ /\/\ /\/\ /\ /\ /\ /\ /\ /\ /\ /\ /\/\/\/\ /\/\/\/\ /\/\/\/\ /\/\/\/\ /\ /\ /\ /\ /\ /\ /\ /\ /\/\ /\/\ /\/\ /\/\ /\/\ /\/\ /\/\ /\/\ /\ /\ /\ /\ /\ /\ /\ /\ /\ /\ /\ /\ /\ /\ /\ /\ /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
