On my way to reading an article by Atul Gawande in the January 24, 2011 issue of the New Yorker, I stumbled on a Talk of the Town piece about an odd electronic instrument called the Swarmatron.
Hadn’t paid attention to it when I first skimmed the magazine three years ago, but it sounds intriguing. Listen to the demo on YouTube, or watch an interview with Trent Reznor, who used the Swarmatron in the sound track for “Social Network.”
