The term "participation" provides a point-of-reference for experimental
software art by Barbara Lattanzi. Such projects as Lattanzi's net-based
"CSPAN Karaoke" emphasize the improvisational and cooperative dimension
of Participation as critical (or ironic) re-figuring of the
human-computer interface. Software such as "The Interrupting Annotator"
derive partly from late-1980s/early-1990s models of media activism,
public access tv, and other versions of community communications. Some
of Lattanzi's projects, such as "EG Serene", involve small-scale,
cine-software applications for video improvisation, that "open source"
key works from the 1970s era of structuralist, experimental filmmaking.
