Swedish design firm People People has prototyped a transparent speaker called "Speaker," which uses WiFi or a headphone jack to receive its signal.
Being big is good for sound quality, but not so good for shipping. Any other speaker will ship a lot of air around the globe before ending up in your living room. This speaker ships in a small, flat package that goes in through your mailbox. The glass sheets making up the box is being ordered through the glass repair shop closest to every single customer. In that way the speaker reduces shipping with up to 90%, and supports local handicraft in one go. A very economical and ecological solution.
The speaker is then assembled at home, IKEA style. This also means that the components that breaks first (the rubber ring and the speaker cone) can be easily replaced, keeping the product away from any landfill.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
