NTT DoCoMo showed off a mockup of a cell phone with a wooden case at Ceatec. The Japanese operator showed off two prototype Touch Wood handsets, including one working model, that have cypress cases at the Ceatec exhibition in Chiba, Japan. The wood used to make the Touch Wood prototypes comes from trees that are felled in forest-thinning operations, rather than being cut for commercial use. The felled trees are then chopped into blocks, which are then cut into the desired shape. The case is then compressed in a mold, using a technology developed by Olympus. The end result is a glossy case that is waterproof and resistant to wood-eating insects and mold, DoCoMo said.
