In an effort to understand what is going on here, I decided to put the code in a more readable format
#!/usr/bin/perl
$_='
$q="\47";
while($; = $z+ =.5){
%c = $r = 0;
$/="";
while(20+$z>($;+=.05)){
$c
{ int $_ + 26 + 2 * ($r += .02) * sin $; }
{ 1 - $_ + 10 + int $r * cos $; }
= 1for(0..1)
}
$t = reverse;
$/ .= `clear` . "#!/usr/bin/perl\n\$_=$q\n";
for $y (1..20){
$c{$_}{$y}
? $/ .= chop $t
: ($/ .= "\40")for(0..53);
$/.="\n"
}
print "$/$q;s;" .chr(92). "s;;g;eval\n"
}
';
s;\s;;g;eval
Quite amazingly it prints the same image in this format. I think it has to do with the sin/cos.
Two things I am unfamiliar with, the $; variable and this line:
s;\s;;g;eval
Big props BTW
