iRock- the power generating rocking chair

from core77: We have added... a generator that transforms the movement into power. We have equipped the iRock with an iPad stand and a set of built-in speakers in the back rest. Over the last couple years, we have come to depend on an increasing amount of technical gadgets...
The iRock is a product that explores how furniture can interact with technology and actually support the power for this technology. Movement is energy and to collect as much of this energy as possible is one of our future challenges.
