iBamboo Speaker

iBamboo is a natural speaker made from a single natural material, bamboo. The natural resonance of the bamboo amplifies the sound produced by the built-in speaker in the iPhone 4. The sound moves in two directions and creates a stereo effect. iBamboo is not available yet, but if you want to keep updated visit their site. What I like most with this product is that it doesn’t use any batteries or yet another power adapter.
