Giselle Beiguelman
«Poetrica»

The epigraph of Beiguelman’s 1999 Web work «The Book After the Book,» reads «at the Intersections of words and symbols we begin to redefine our boundaries...» and in it she writes about the mix of phonetic and non-phonetic substrata in a hybrid digital-analog culture. Much of her work since then deals with many of the same themes and issues, including «Poetrica» (2003), which involves a series of visual poems written with nonphonetic fonts using dingbats and system characters and displayed in a variety of ways such as DVD, digital prints, and movie trailers. Beiguelman also used three commercial electronic billboards located in downtown São Paulo to allow the public to compose visual messages and submit them via the Internet or SMS. In Berlin she restaged the teleintervention on an electronic billboard.
