For the Leeds Pavillion at Mediamatic’s Amsterdam Biennale 2009 Pst! chronicled life in Leeds through it’s twitter feed. The movie below provides the run down:
The piece locates a public social narrative by pulling an information feed from Twitter User profiles geographically aligned to Leeds with Twitter’s geocode API and then prints this information onto a mini LCD screen. By removing the peripheral of the computer a Pst! device can be placed in a non-space providing a window directly into a geo-located public space.
