    AGN with the so-called `double-double' radio structure have been interpreted as restarted AGN where the inner structure is a manifestation of a new phase of activity which happened to begin before the outer radio lobes resulting from the previous one had faded completely. The radio galaxy 1245+676 is an extreme example of such a double-double object - its outer structure, measuring 970 h^{-1} kpc, is five orders of magnitude larger than the 9.6 h^{-1} pc inner one. We present a series of VLBI observations of the core of 1245+676 which appears to be a compact symmetric object (CSO). We have detected the motion of the CSO's lobes, measured its velocity, and inferred the kinematic age of that structure.Comment: A contribution to The Third Workshop on Compact Steep Spectrum and GHz-Peaked Spectrum Radio Sources, Kerastari, Greece May 28-31, 2002.

    Stickers as a Literature-Distribution Platform

    Contemporary experimental writing often directs its attention to its writing space, its medium, the material on which it is presented. Very often this medium is meaningful and becomes part of the work – the printed text transfered to another media context (for instance, into a traditional book) would become incomprehensible. Literature distributed on stickers is a form of writing that is divided into small fragments of texts (a type of constrained writing), physically scattered in different locations. One of the newest challenges in literature are books with augmented reality, AR, which examine the relation between the physical (the medium) and the virtual interaction. Sticker literature is a rather simple analog form of augmented reality literature. The stickers have QR codes or web addresses printed on them, so the viewer who reads/sees a random sticker in the public space can further explore the text online. The viewer can read other parts of the text on photographs (the photograph being another medium) of other stickers placed in different locations. The author will discuss the use of stickers throughout literary history, beginning with 20th century French Situationists, through different textual strategies applied by visual artists and ending with literary forms such as the sticker novel Implementation (2004) by Nick Montfort and Scott Rettberg or Stoberskiade (2013). The author shall try to explain why writers decide to use this form, how the text is distributed and received and how the city space is used in such projects

    Textual Demoscene

    The demoscene is a mainly European subculture of computer programmers, whose programs generate computer art in real time. The aim of this report is to attempt a description of the textual dimension of the demoscene. The report is the effect of efforts to perform an ethnographic exploration of the Polish computer scene; it quotes interviews with participants of demo parties, where text plays a significant role: in demos, real-time texts, IF, mags or digital adaptations. Media archeology focusing on the textual aspect of the demoscene is important to understanding the beginnings of digital literature and genres of digital-born texts
