Just curious if anyone has come up with some cool ways to display all of your certifications?

I currently have 5 different ones and some of my co-workers also have some.  We decided we would like to display them in our office area, however we are looking for a creative way to do so vs. just printing them off and sticking them on the wall.

Has anyone done anything special (engraved plaque, laminated display, etc) ?

Thanks in advance!
