Looking for a cheap and easy iPod speaker? Bird-Electron has created a speaker kit that allows to reuse Apple's plastic packaging and create a simple, yet stylish, speaker.
Simply pop the speaker panel into the box, plug in your iPod, and you're good to go. Any container will work if you've already disposed of your box, including a water bottle as pictured here. The speaker box is made by the Japanese company, Bird-Electron, but AudioCubes carries the kits for $40.
