Love Post Office has been always the symbol of Zhuhai, Guangzhou Province, P.R.China. Giant Wood Agency approached Digital FUN to change the traditional Post Office into a visual nighttime destination. They wanted an interactive solution for presenting multiple types of media at once, documentary video, artistic motion graphic design, and business and real-time video games. The result was a 30-meter by 4-meter huge LED-based installation. Digital FUN added LED transparent screens to the existed window of the whole office. By creating a new interactive communication system between the structure and visitors, we offered an experiential connection between the people and place. After scanning a QR code visitors would be able to ignite fireworks on the huge screen with their mobile device.
