I bought myself a small shadow box display for my pin(s) today. I got Disney scrapbooking paper to use for the background in it.

I'm going to hang it in my office after I get enough pins to make it worth displaying (it looks a little pathetic with just one pin in it).
I also got a Disney patterned vellum paper that will fit over the window in my office door (it's just one of those 10"x10" windows...since my office is right next to the conference room, I want to keep something covering the window so everyone isn't staring at me as they walk past, but the previous occupant had just plain solid paper on it, and I wanted something fun and a little translucent so folks know I'm in there when the light shines through (at least until I can get the automatic closer thing off the door so I can keep it open a crack when I want people to know I'm there).
I'm still looking for more colorful stuff to decorate my very plain, ugly walls. I already got a poster of a window (since I don't have a real window)...the post-docs are telling me I should put up curtains and a window box filled with plastic flowers. I just might do that to be totally silly...when you're in a place where offices with windows are at a premium, you have to have a sense of humor.
