Have you ever thought of placing your logo on your office wall?
I recently had this idea for my own office, and I was able to incorporate it recently into a client's design for her new office. We used a vinyl plot machine to produce hers, but you could easily paint your logo (or hire someone to paint it if you're not a DIYer!)
Depending on how big or small you wanted your logo, you could also design a stencil and stencil one logo, or you could space them out and make it look like wallpaper. Wallpaper is back in style, baby!! So get creative!
