WOODSTOCK '94 Time Capsule
In 1994 the internet was just beginning to seep into public consciousness. But in August of that year volunteers set up a tent filled with net-connected computers in the mud of Woodstock '94 and set up a website to record the impressions of the concertgoers.
It was easily one of the earliest publicly-oriented internet events and the website remains online virtually untouched since. Its bare text layout and simple message system are definitely archaic and you can glance through the messages for people's feelings on both the Woodstock event as well as the burgeoning internet.
It's a unique time capsule and certainly gives a distinct impression of a cultural perspective that's been worn away by two decades of digital erosion.
