The last time I visited SLAC was about a decade ago. They were busy building the nearly perfect aluminum coated quartz spheres that are the essence of the free rotor gyroscopes flying on Gravity Probe B. I think the analogy regarding the sphericity was something like "if the spheres were as large as the earth, the difference between the lowest ocean trench, and highest peak was on the order of a few yards".
