Or, since you're just taking the chr value of each of those numbers, just use map:

my @whirley = map chr, qw/32 176 177 178 219 178 177 176/;

Then you don't have to bother with split and all that.

Also, the whirley function could use some work (particularly since it gives a warning):

sub whirley {
    $WHIRLEY_COUNT = 0 if ++$WHIRLEY_COUNT == @whirley;
    return $whirley[$WHIRLEY_COUNT];
}

The most important change here is the return line. You were taking an array slice:

    return "@whirley[$WHIRLEY_COUNT]";
[download]

which isn't what you want to do; you just want a single element (and you don't need the quotes):

    return $whirley[$WHIRLEY_COUNT];

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).
