I think the most attractive solution would be using either a server-side scripting language or jQuery to automatically apply the effect shown in the uncyclopedia link to arbitrary content. I gather the essence of it is this:
<div style="position:relative;letter-spacing:2px;">
<p style="position:absolute;left:-2px;color:#f00;width:100%;">Text</p>
<p style="position:absolute;left:2px;color:#0ff;width:100%;">Text</p>
<p style="position:absolute;left:0px;color:#000;width:100%;">Text</p>
<p style="visibility:hidden;">Text</p>
</div>
If you don't need to support non-Javascript clients, a jQuery solution would be preferable because the text content would remain properly indexable by search engines, and readable by screen readers. Also, you could have a "Turn 3D on / off" switch.
