Taking an entertainment center on the road can be a pain, as even the smallest portable speakers weigh a pound or two and take up valuable space. Chicago-based OrigAudio has come up with an ingenious solution: self-powered, 1-watt speakers made of heavy-duty recycled paper. Assembly is easy: simply fold the paper into a 3-in. (7.6 cm) cube. For travel, unfold it and slip the flat sheet into your laptop sleeve. Sold through the company's website, Origaudio.com, and at select retailers, the speakers ($16 a pair) can be hooked up to any audio device with a headphone jack. Part of the proceeds supports the nonprofit Music National Service, which brings music to public schools and low-income communities. Origami has never sounded so good.
