Editor's note: Brought to life almost exclusively by Arnold Schwarzenegger's dream of making the military vehicle Humvee available to the civilian public, the Hummer is a lot like the bodybuilder/movie star/politician who backed it from the start: larger than life, insanely strong, a little over the top but extremely fun. Thanks to a booming economy and low gas prices when the Hummer was introduced, it not only took off but became a symbol of the happy excesses of the early 2000s. Celebrate the Hummer with a wallpaper from this cool collection!
