At first glance, the Novague concept is a slick update to the timeless rocking chair. But housed in the base is a kinetic motor that powers an LED light using the chair's natural rocking motion.

Sure, this one doesn't have a pair of nuts, but it'd be self-sustainable if it ever leaped from the drawing board.

Note: Realistically, this chair would be more work than it's worth, given the amount of rocking one would have to do to keep that LED lit long enough to read a pamphlet, let alone something a bit more meaty. Like something on a Kindle 2, for example, because it doesn't have a backlight. [Dezeen]
