This seems like a good Friday post - drink coasters. And not just any drink coasters, augmented reality drink coasters designed by our friends at Atomic Playpen. These ephemera inspired coasters were sent out to Atomic clients in a metal case. There are four coasters inside, each with a different marker on the back side. The instructions direct you to their anniversary website where you hold up one of the markers to your webcam and enjoy the action. (If you don't have a coaster from Atomic, you can still print a marker at the site and give it a try.) We letterpress printed them on 60pt blotter board with very dense black ink coverage so the marker would work properly. The sheet was then die cut into the four coasters. So cheers, we'll have another round and add it to our beer wall.
