The recently published book, Tales of the San Francisco Cacophony Society is a historical accounting of just what the Cacophony Society was/is and how their antics in the 80's & 90's have inextricably influenced our popular culture today.
The tech and media website, CNET, wrote a great mini history in this ARTICLE.
