Taking it one step further here is a repackage of btrott's version that takes an argument to choose from an array of weird spinners.
# main
my $whirley = Whirley->new(1);
while (1) {
sleep 1;
print STDERR "please wait: ", $whirley->(), "\r";
}
package Whirley;
sub new {
my $type = shift;
my $number = shift;
my $class = ref $type || $type;
my $WHIRLEY_COUNT = -1;
my @whirleyhash = (
[qw(- \ | / )],
[map chr, qw/32 176 177 178 219 178 177 176/],
[qw(>--- ->-- -->- ---> ---* --- ---< --<- -<-- <--- *---)],
[qw(_o_ \o/ _O_ \O/)],
[qw/. .o .oO .oO(zzz) .oO(ZZZ) /],
[ '(^_^ )','( ^_^)'],
[ '(^_^ )','( ^_^)','( -_-)', '(-_- )' ]
);
my @whirley = @{$whirleyhash[$number]};
my $self = sub {
$WHIRLEY_COUNT = 0 if ++$WHIRLEY_COUNT == @whirley;
return $whirley[$WHIRLEY_COUNT];
};
bless $self, $class;
}

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).
