Re+Public [Heavy + PAC] traveled to Brussels, Belgium to participate in a tech art summit / workshop organized by the European Union Commission, IMAL, and the Harlan Levey Projects [bridge]. During the five day stay in Brussels, we seized the opportunity to digitally takeover Grand-Place, a UNESCO World Heritage Site. We successfully built three mobile augmented reality functionalities: interactive augmented mapping, interactive data visualization, and a digital art installation.
