A master at combining aesthetics and mechanics, artist Jonathan Schipper recently joined forces with fellow artist Amelia Biewald to create a stunning metal iPhone case that they've dubbed Exovault.

Made from solid aluminum, brass or titanium, the handcrafted cases lend a steampunk look to the device—a big step up from the plastic varieties that house most iPhones today. Over time, the lustrous surface will develop a uniquely exquisite patina, making the durable casing that much more appealing.

Accustomed to working with a variety of materials, the duo has collaborated on projects before, resulting in compelling installations such as "Firebird," a raven-filled tree comprised of parts from a 1969 Pontiac Firebird.

Designed in Brooklyn, New York, you can purchase the cases from the Exovault website. The aluminum and brass versions run $95, while the titanium version will set you back $300. To inquire about custom versions email exovault [at] gmail [dot] com.
