This code is on six packs of Heineken. When you scan the code you get a free app from them for your iPhone or iPod. It's pretty clever. Now it's not exactly a "QR" code but it's still a scan life code. But in case it doesn't count, I found another one.
It's a movie poster for 28 weeks later. The code takes you to the movie's website. And if you look really close you can see they put the 28 week sign thing in the very middle of the code.
