The aim of the campaign was to find another unorthodox way to strengthen already existing marketing activities undertaken by our client, all the while brightening dreary winter days and giving the good people of Warsaw some positive energy. Thats how the artificial sun on the Q22 skyscraper in the Warsaw City Centre came to be. We realised the project using Ambient 2.0 mechanics, linking offline activities with those occurring online in order to gain maximum reach and to engage the entire city. Our collaboration with the Instytutem Optyki im. Profesora Maksymiliana Pluty (INOS) came to life and our project partner was Echo Investment, the owner of the Q22 skyscraper.
