[jQuery] Overlay plugin?

[jQuery] Overlay plugin?

<span style="font-family: verdana;">I can't find it, but I vaguely remember someone had a plugin that just puts a 50% opacity overlay over the page.
Sort of like a thickbox thing, but without all the other stuff.<br style="font-family: verdana;">
</span><span style="font-family: verdana;">Does anyone know where it is?</span><br style="font-family: verdana;"><br style="font-family: verdana;"><span style="font-family: verdana;">Glen</span><br style="font-family: verdana;">
