The museum's design team did the 3D modeling for 28 sheet metal panels that serve as a base for the Nanoleaf Aurora panels. A local fabrications shop used the models to guide a plasma cutter to precisely cut the detailed shapes, and then bend the resulting metal pieces into the final shapes.
The 28 panels form 12 equilateral triangles (each with 81 Aurora panels) and 4 parallelograms (54 Aurora panels each), for a total of 57 feet 11 inches (17.6 meters) long and 6 feet six inches (2 meters) high, and 1,188 Aurora panels.
The use of a metal base allowed us to use small magnets glued to the back of each Aurora panel for attachment. This allowed us to easily move each panel into position and make small adjustments as necessary, and would also allow for easy repairs in the event of a panel failure.
