Make your desktop a source of pride every start up with a hi-def desktop wallpaper. These grunge flag backgrounds from Awesome Wallpapers come in a wide variety of screen resolutions as a single .zip file in groups updated every week. If you don't see your country in this list, try checking out the other flag sets: Grunge Flag Sets.
Carry your Olympic pride wherever you go with one of these smartphone wallpapers for your home and/or lock screen. This collection offers a majority of flags in a layout easy to browse and download directly onto your device. Although the site caters to iPhone, the image collection is easily used by anyone on Android, Windows Phone or Blackberry devices too.
If you're willing to spend a little more, you can show off your pride with an actual physical item to fly your flag of loyalty. Zazzle offers a collection of flag themed laptop and tablet sleeves come in a variety of nationalities in sizes designed for tablets all the way up to 17" laptops.
Smartphone skins are my favorite options, since they're both easy on the wallet (usually $6.99) and let you show your national pride wherever you take your smartphone. Android and iPhone users of almost any nation have options to cover both the front and back of their smartphones (plus they're removable). Just be sure to match it with the customization below and a wallpaper desktop above for the full effect.
Instead of simply showing off your Olympic allegance, why not let it be heard any time you receive a call? Here's an iTunes collection with 67 different countries' national anthems, from Algeria to Zimbabwe. Of course, if you want to represent in the global spirit of the games, you can always load up the Olympics anthem as goodwill gesture.
