This probably isn't fair without some clearer code to start with. This is based off the authors original C code.
#! /usr/local/bin/perl -w
use strict;
my $fVRR = -2.3;
my $fVRI = -1.0;
my $fMaL = 0.05;
for (my $i = 0; $i < 40; $i++)
{
my $fCI = $fVRI + $i * $fMaL;
for (my $j = 0; $j < 60; $j++)
{
my $fCR = $fVRR + $j * $fMaL;
my $fZR = $fCR;
my $fZI = $fCI;
my $bI = 1;
for (0..255)
{
my $fZRS = $fZR * $fZR;
my $fZIS = $fZI * $fZI;
if ($fZRS + $fZIS > 4)
{
$bI = 0;
last;
}
$fZI = 2 * $fZR * $fZI + $fCI;
$fZR = $fZRS - $fZIS + $fCR;
}
print $bI?" ":"+";
}
print "\n";
}

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
