On the theme of using the packaging as part of the product, a designer by the name of David Gardener has created a packaging lamp. The packaging lamp houses all the parts you need to make a lamp from the packaging.
The material itself is made from recycled cardboard pulp, and there is no waste whatsoever. The bulb and wiring is housed in the packaging until the lamp it put together. I must admit, this lamp looks pretty cool!
