At first glance, Katena might look like an ordinary inflatable with an unusually complex and oversized structure. But when they walk inside, visitors soon realize this is an entirely different experience. They enter a world apart, a world of interconnecting tunnels and domes saturated with light and color, called a luminarium. This video will take your students on a virtual tour of one luminarium that was featured at the Cincinnati BLINK festival. They will learn how the design team of Architects of Air blends geometry, art, and architecture to create a pneumatic, or air-filled, structure in which form must follow function.
