View Signature hack

[TMXS]

I'm looking for a hack which will place something along the lines of "View Signature" where a user's signature would normally be. When clicked, the link would pop-up a layer (not a page, but a layer) with that signature and when a "close" button is hit, it would disappear. I realize its not a difficult hack to make but am wondering if someone competent at php wants to give it a go before I make a mess of things by trying to write it myself.

This hack is for the purpose of making the forum appear more professional not only to registered users who have the option of switching sigs off and on but to everybody. I realize it may not sit well with younger users who tend to express themselves with their sigs but I'm willing to take that chance. I'm sure there are others out there who feel the same way.

Anyways, if anyone is willing to help out and write this hack I'd appreciate it.
