Let them eat QRcakes. Or cookies, rather.

German company Qkies.de will bake you a special batch of QR cookie decorations, where the code itself can lead to a web page, a flickr-image, a youtube-video, anything you want anywhere on the web really. You order the cookie-mix for a cheap 6.90 euro and receive a box with enclosed QR codes printed on edible paper that you can decorate your delish with. Now all I have to do is find a company that bakes the cookies, because I know I fail at baking from mix every time. It's a curse.
