Actually, the rolling ball is not a voodoo science. It actually came from building construction engineering. I was working at an architecture firm about 10 years ago when I first got out of school, an engineering firm came to do a presentation on the then new San Francisco Library that they had just constructed using this type of seismic technology. Each of the column has a "ball" bottom, and sits in a cup, so that when earthquake hits, the entire building will sway laterally as a unit, and prevent the building from collapsing. This technology was widely used in earthquake prone areas like Tokyo.
I've read some white papers on these ball/cup combo tweaks for audio, and they seem to build on the same principle to combat lateral vibration.
