I’m not sure how well cases with holes will actually protect your iPhone, but since there are some available from major manufacturers, they must help at least a little, right? If you don’t mind having a case with holes in the back, then check out the 3D printed Ripple case.

The Ripple case design was obtained after modifying one with straight lines. The series of curvy opening creates a pattern which produces a sort of 3D optical illusion, which is definitely unusual.

It was created by Spaho Design and it’s available through Shapeways for $30(USD), and you can choose from a number of different materials if you’re going to get one.
