For the annual event "Dj op de Dom" we collaborated with the talented team of Born Digital to create an event on the famous and remarkable Dom Tower of Utrecht. In this special open air event we surprised the audience by changing the ancient church tower into a VJ screen. Together with about 8000 people we celebrated the 300 years freedom of Utrecht. The animations were partially mapped and synced with full color led lights which went all the way up to the highest point of the tower. This made the gathering visible for almost everyone in and around the city.
