Stylish Smilies adds CSS classes to text-based emoticons. 
You can then reference these classes in your theme to style each emoticon differently:
<pre><code>.smiley {
/* Applies to all emoticons */
 color: black;
 font-weight: bold;
}

.biggrin {
/* Applies to :D only */
 background: green;
}
</code></pre>
This plugin affects the following smilies:
<pre><code>8-) cool
 8O eek
8-O eek
 :( sad
:-( sad
 :) smile
:-) smile
:-? confused
 :D biggrin
:-D biggrin
 :P razz
:-P razz
 :o surprised
:-o surprised
 :x mad
:-x mad
 :| neutral
:-| neutral
 ;) wink
;-) wink
</code></pre>

WP Figlet allows you to draw ASCII art in your posts and page source.
Here is an example:
<pre>
 __ __ 
| | _ _ _| |__) _ _ _ _ |__) _ _ | _ | 
|/\| (_) | (_| | | (- _) _) | \ (_) (_ |( _) . 
</pre>
You can use ASCII art to say a personal message about your site. Or it can say an advertisement.
This can be especially true for web design or development sites or if your site just plain rocks, as often people like to take a look at the page source to see how was something done or what plugins were used. This ads just a little extra touch of coolness that might persuade them to actually give you that call. Of course there are ton?s of fonts and you can customize is the way you want.
