The Windows 7 burger is region-locked to Japan. Fortunately one amazing hacker found a way to hack the sandwich for region-free consumption. You're looking at the results: the world's first unlocked cheeseburger.
This hacker also accomplished what may be the world's first burger jailbreak. There's a ton of functionality added in like cheese and extra sauces, the kind of stuff the stock build can't touch.
Instructions on how to hack and unlock your own Windows 7 burger are provided at the link. Please, head over and give this a digg. Work this great more than deserves it. [Eating the Road](Thanks, Samuel!)
