Every day, an endless stream of tweets enters the Twitterverse - some to live on via retweets and favourites, others to fade into the dark depths of the web, never to be seen again. This "here today gone tomorrow" phenomenon led us to wonder: must digital chit chat be so fleeting? We didn't think so. And thus, Knitterstream was born. It began as a data visualization project - an electronic knitting machine from 1998 that, with the help of custom software and hardware, could transform a humble tweet into a tangible, real life, woven work of art.
