This is a tricky one. What's the QR Code on that flag our little Android friend is waving?
Turns out the QR code that leads to a game on the Android site, where you can play a Nexus-One-only game of Android-themed memory.
It's basically that classic game in which you have to find the pairs of cards with matching icons, except here the icons are adorably dressed Android logos. By the way, it's supposed to be limited to users of the Nexus One, but, well, it's pretty easy to get around that. Phandroid has instructions if you're interested in playing.
