The Deutsche Telekom hosted the world’s largest digital derby in Cologne and Düsseldorf last week. In the digital version of “High striker”, 60 companies and 10 schools competed against each other. The two radio towers, the Colonius and the Rheinturm, acted as illuminated digital indicators. Intermediate engineering realized the technical planning in advance and the technical management of the projection and playback on site. The project was implemented in cooperation with Urbanscreen (content design and creation).
