I put a facebook badge on my Windows Live Spaces site the other day as I couldn't find any (working) facebook gadgets for Spaces in the Windows Live Gallery.
It was a fairly easy process but as I couldn't find any how-to's on the net I've written one myself in case anyone out there needs a hand.
A facebook badge (by default) shows a thumbnail of your profile picture, your name and the networks you belong to. It also links back to your facebook profile page.
