If you're a fan of laptop skins, then Tamara Rodger's design is a good choice. It's available for a wide variety of Mac and PC sizes, as well as the iPad. While it doesn't offer a ton of physical protection, the vintage Union Jack juxtaposed with the Olympic rings should make any Brit proud.
Of course, there's all kinds of other subtle ways to bring the Olympics into your office space. I love Alejandro Giraldo's skull design (1) for this reason. For whatever reason, in my mind I imagine it could also double as the album art for Sex Pistols Olypmics tribute track. It's available as a framed print, stretched canvas, stationary or an iPhone skin.
I know what we're all secretly thinking. Quidditch should have been added to the Olympics roster this year. For $35.65, you can pretend like it's happening by snapping this Society 6 case (2) on your iPhone.
I'm into old school stationary. I think it's important to send people a personal note every once in a while, so I keep a big stack in my desk. These Tower Bridge 2012 cards (3) would be a great addition for this summer.
The messenger bag is the go-go gadget bag of the modern office warrior. This unisex, vintage inspired, bag from the Olympics shop (4) commemorates the 80s Olympics in Moscow. At $43.50, it's not a bad deal either.
