The Time Machine Minigolf in the Blue City shopping center is a unique place on the map of Warsaw. This is not an ordinary miniature golf but a specially designed place where visitors can move themselves through time. The decoration is stylized for different eras and places, and for further awakening the imagination one can wear 3D glasses. As a part of the public-address installation at the Time Machine Minigolf Biamp products were selected for their ease of installation, operation and reliability.
