chthonic ambiance

More quake celebrations are going on in SF, now at the Exploratorium, within a magnificent classical Roman complex built in 1915 for the Panama-Pacific International Exposition (photo to follow). A new exhibit at the museum where I attended my junior prom with my best friend Janice, contemplating neutrino tracks and blowing giant bubbles while dressed in ballgowns, allows you to hear sounds created by the movement of tectonic plates, although my quick skim of the article didn't reveal how the sound is reproduced. Chthonically cool.
