Best viewed in HD! The "nerdglasses" made meaningful! Even though the smartphone and services like Runkeeper and Nike+ have transformed our training into something more social and made it easier to track our progress, a smartphone on the arm, or in the hand, while exercising is still a quite awkward situation. While these services are more focused on the post workout experience, we have created a concept which can make the actual running, skiing, biking or other workouts more meaningful and fun, using the Gosta glasses. The name is a tribute to former Swedish runner Gösta Holmér, the inventor of Fartlek. A type of interval training.
