Twitter logo as link in menu bar

Hi, Tom:

[GP Premium, current version.]

I've tried and failed to figure this out, so I'm begging your help.

I'd like to add a link to my site's Twitter account into the menu bar at the right roughly where the search box would appear if I had it activated (which I don't).

Except that I want to use the Twitter logo as the link, rather than text.

I see how to add a logo to the menu using MenuPlus, but that's just a graphic, not a link, and I'm not using MenuPlus for anything else.

What am I missing? I can't turn a graphic into the title of a page and add it to the menu that way with a custom link.

Stymied. Thanks in advance for your help!
