Valser is one of Switzerland's oldest and most recognized mineral water brands. Each drop is filtered for 25 years through 1000 meters of solid rock. To bring the brand to life, we created the world's first kilometre deep website. Starting at the top of the mountain, browsers can click on a topic of interest and are "elevatored" down through the layers of rock to information, links, sounds and images. They can also click anywhere on a timeline icon and be surprised at where they end up. Browsing down, they are continuously reminded how far they've gone and how many years have passed.
