In March of 2003 the City Aquarium team flew off to Copenhagen, Denmark with Tony Oursler. Oursler had contacted CA to design a tank for his new exhibit "Unk". We fabricated an acrylic and fiberglass reinforced plastic (FRP) aquarium and had it air freighted to Aarhus, Denmark for installation. The aquarium, a 6' x 6' box, was placed in the "9 Rooms" exhibit in the new Aros museum.

City Aquarium installed the tank and hooked it up to a water clarifying system we developed to maintain crystal clear water. We helped Oursler position his sculpture and set up his installation piece. Oursler created a hologram by using a combination of water, light, and projection. "Unk" is truly amazing, even with no fish.
