In the 1980s, the world saw the introduction of personal computers (PCs). While the first creative stage of electronic literature took advantage of mainframe computers, only accessible in institutional environments, the context in which Silvestre Pestana created his first computer poems was totally different – a new wave Pedro Barbosa ironically calls “poesia doméstica” [domestic poetry] (1996: 147). With personal computers, Silvestre Pestana programmed in BASIC, first for a Sinclair ZX-81, and then, already with chromatic lighting, for a Sinclair ZX Spectrum, three poems respectively dedicated to Henri Chopin, E. M. de Melo e Castro and Julian Beck, which resulted in the Computer Poetry (1981-83) series. Pestana, a visual artist, writer and performer – who had returned from the exile in Sweden after Portugal’s Carnation Revolution of April 25, 1974 – brought diverse influences put forward with photography, video, performance, and computer media. From his creative production, it should be emphasized the iconic conceptual piece Povo Novo [New People] (1975), which was remediated by the author himself in the referred series of kinetic visual poems, “video-computer-poems” (Pestana 1985: 205) or “infopoems” (Melo e Castro 1988: 57). By operating almost like TV scripts, the series oscillates between recognizable shapes – such as the oval and the larger animated Lettrist shapes, formed by the small-sized words “ovo” (egg), “povo” (people), “novo” (new), “dor” (pain) and “cor” (color) – and the reading interpretation of the words themselves: “ovo,” the unity, but also the potential; “povo,” the collective, the indistinct, the mass; “novo” and “cor/dor.” This play of relations translates the new consciousness, although painful, of a “new people” in a new historic, social and artistic period, one of freedom and action. In an interview, Pestana (2011) claimed having researched more than thirty languages, only to find in Portuguese the possibility of traversing the singular and the plural, the individual and the collective, the past, present and future, by just dislocating a letter: ovo/(p)ovo/(n)ovo.
E. M. de Melo e Castro has written poetry in different physical media – in the same way as “peso pesado do átomo” [atom’s heavy weight] (Castro 2006) – such as paper, textiles, canvas, wood, metal, stone, plastic, early opting for a dematerialization of word and image, something that became apparent, from the outset, in the pioneering videopoem Roda Lume [Wheel of Fire] (1968). This dematerialization of the artwork was taken as a guideline for the retrospective exhibition “O Caminho do Leve” [The Way to Lightness] (2006) at the Serralves Museum of Contemporary Art, in Porto. Melo e Castro states:
