Twig Case Co. in Minnesota makes nice iPhone cases out of paper and bamboo, including this beautiful Jim Woodring model, called "Frank in the Tempest."
The founder of Twig Case, Jon Lucca, is an illustrator, too, and I really like his art on "The Bunker" bamboo case. I saw a little easter egg in it that made me smile! (Click thumbnail for enlargement.)
