To celebrate the launch of the Lumia 800 in Denmark, Nokia and carrier Telia have teamed up to pull off an interesting stunt - the "Human Keyboard". We've previously seen the scale of the country's Lumia handset launch with an event being held in Copenhagen back in January, but it's good to see carrier support added in.

The Human Keyboard features a keyboard mat laid out on the pavement in front a store. We then have five musicians stood in the store window who play corresponding music notes with instruments in the attempt to match the members of public who step on the mat.

Of course, you'd have to have some fun and try to trick the musicians, which is exactly what we see in the above video. You can purchase the Lumia 800 in cyan at the Telia online store.
