On New Year’s Eve, the roof of Vienna’s St. Stephen’s Cathedral was the centre of A1’s celebration of the launch of 5G. Together with laserfabrik we created and executed an interactive marketing campaign that allowed visitors to Vienna’s New Year’s Eve Trail (Silvesterpfad) to project their best wishes to the roof of  St. Stephen’s Cathedral. More than 1,000 messages – including wedding proposals – were projected onto the roof by eight high-performance lasers high above St. Stephen’s Square.
