Does a badge for members exist?

HI!!
I have a forum using buddypress, but people have to sign up though membership to access the forum. I have different subscriptions available. (1year member, lifetime member, professional member)
I am trying to figure out a way to have a badge of some sort on their profile page and/or a ribbon on their avatar on the different subscription levels.
So, if someone is a lifetime member they would have some way to be recognized as such in the forum.
Any suggestions?
Thanks!
