Horizon is a participatory art project at the annual MaD (Make a Difference) Forum in 2014. It was an art process reflecting on the notions of sharing and exchange. Through the exchange of glass vessels that were used as admission tokens to different activities, 1,500 attendees shared limited programme places. Participants also got water from a sculpture, shared with one another, and created a symbolic horizon across the glasses. The sculpture, a set of intricately connected bottles, also featured a horizon with water in all bottles constantly leveled.
