Mobile carrier O2 has launched an interesting project, the aim being to capture the prevailing mood in German cities – based on
keywords from social channels and using sophisticated technology. Brightly animated icons – birds, hearts, flowers, etc. – designed to represent different emotions move across the screen to the sound of music. The archive can be used to track the mood in recent weeks and to compare different cities with one other.
