World's Largest Reproduction of Human Vertebrae?

To celebrate chiropractic's centenary, Ari Diskin, DC, of Melbourne, Australia, commissioned the construction of two vertebrae (approximately 15,000 times larger than life) for display outside his practice. The vertebrae are constructed of plaster, coated with fiberglass, weighing in at 1,000 lbs. The two bones measure 5' wide x 5' deep x 4' high, and sit atop a stand. The sculpture also simulates spinal nerves, one with a steady flashing yellow light (healthy nerve), and one with an intermittent flashing red light (irritated nerve).
