News: Indestructible iPhone 4 Case Inspired by Shark Eyes

It's not uncommon for nature to inspire technology and innovative products. Airplanes were inspired by birds, Velcro by burrs and dog fur, bullet trains by owls and kingfishers, and gecko tape by... well, you can probably figure that one out. And one of the deadliest fish ever to swim the oceans has also influenced its share of merchandise; Sharks made humans faster in the water with Fastswim Suits, and now they've helped make one of the most rugged smartphone cases in the world—SharkEye's Rugged iPhone 4 Case.

When it comes to smartphone protection, SharkEye's Rugged Case for the iPhone 4 has got to be the most durable one ever produced. Inspired by the shark's nictitating eyelids which create a clear membrane barrier between immediate danger and their vital vision, the Rugged Case rolls out a semitransparent frosted cover over the touchscreen to protect it from scratches. But it doesn't make it completely unreadable, so you can still see who's calling.

The Rugged iPhone 4 Case goes for $49.95, and aside from the retractable screen, it features a hard outer shell, soft inner lining, maneuverable plug ports and belt clip. The size seems like overkill, making the impressively small iPhone look like a bulky mobile from the '90s. But if you have a tendency to break your iPhone, then you should probably look past the size and think of the money you'd save on glass repair costs.
