I just decided to explain your obfu, so.... here it is:
here is the code in a little bit nicer format with nicer variable names:
$character = "0"; #character to print
@howmany = (
[4,2,4,2,3,3,1,4], #layout of "0" and " "
[1,2,1,2,1,5,1,2,1,2,1,4],
[4,2,4,2,3,3,1,4],
[1,5,1,5,1,1,1,3,1,4],
[1,5,4,2,1,2,1,2,4,1]
);
for ( 0 .. $#howmany ) { # loop through @howmany
foreach ( @{ $howmany[$_] } ) { # loop through the arrays of @how
+many
for ( 1 .. $_ ) { # print $character the number of times spec
+ified by the item of an array of @howmany
print $character;
}
if ($character =~ /^0$/) { #switch $character from "0" to " "
$character = " ";
} else {
$character = "0";
}
}
print "\n";
}
each array in @ howmany is the sequence of "0" and " " used to make the out put "PERL", ie. since the first line is
0000__0000__000___0____
note "_" eq " "
since there are four "0", two " ", four "0", two " ", three "0", three " ", one "0", and four " ", you get the array:
4,2,4,2,3,3,1,4
. Etc. etc. The loops go through each array of @howmany, printing the value of $character, which changes after every item in the array of @howmany from "0" to " " using the if statement.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
