For many, the return of air travel meant moving from isolated existence to a mélange of uncertainties, along with visions of swamped airport terminals and planes packed with bodies. For people traversing Sky Harbor Airport, several artworks installed as terrazzo flooring provide a visual break from travel worries or stress. That's particularly true for From the Earth to the Sky, the 6,000-square-foot design that channels the energy and movement in Bill Dambrova's larger body of work, which trains the eye on what he describes as "our biological and metaphysical relationship with plants, animals, the cosmos, and each other." Walking atop his colorful design filled with natural forms, travelers feel a sense of wonder and joy. But the artwork is also a reminder that all those people we sometimes find so maddening in airplane aisles or restroom lines are fellow travelers on a journey through a magnificent desert that's best enjoyed by being curious and kind.
