Shwood Sunglasses  ($95) are handcrafted from actual wood. Available in two basic styles, the Wayfarer-like Canby and the more squarish Govy, and can be ordered in a variety of different woods, along with your choice of Carl Zeiss lenses. Maybe not as practical as plastic or metal frame sunglasses but they are undeniably cool and different.
