With Your Coca Cola Christmas Decoration you can virtually decorate your house, school, or any other building in the world.
You enter the address of the structure you want to decorate and then a satellite image comes on the screen. Next, you choose various Christmas lights in different forms (reindeer, etc.) or design your own on it. Email your creation to yourself or a friend, post the link on a teacher/student blog or website, and then describe it as a language-learning activity. The address itself of the building is not shown in the link — only the decorated building.
It does seem to take a few hours for an email containing the link to reach your mailbox, but other than that slight delay it seems to work pretty easily.
