Very very cool rocking chair by Pouyan Mokhtarani.  My grandma would totally love this!

This is an anatomic rocking chair.  The main idea is taken from a magnificent super human body. This chair is designed in a way that when ever an individual sits on it, he or she will experience the sense of power. This feeling is synonymous to that of a super metaphysic human who can control every surrounding matter. There are 8 liquid pillows in the back which resemble the formation of 8 abdominal muscle packs in human anatomy and two larger liquid pillows in the bottom that resemble the hunkers muscles in the human body.
