Now that everyone is talking about the iPad, I want to demand some attention for the good old 3G and 3GS with this amazing piece of art. The walnut iPhone case is handmade in Portland, in the U.S. and is made of two pieces that slide and lock with its tension catch.
I haven't tried them myself but they look really neat, because combining two different tones at this level requires a lot of skill, and yes, it does look cool. It reminds me of the wooden cases for my iPod video, which were much more expensive. If you have an iPod Touch, the Etsy seller Substrata has more designs that protect the screen.
