  Graphics & sketches


These graphics are made from photos, subjected to postprocessing via various transformations. The main intention of processing is to uncover some 'deeper' content (both semantic and structural) of the graphics, when the rudimentary 'realistic' content of the photo ceases completely or sufficiently strongly, so that the pulsation of the noise (always raising from the original photo) becomes a semiotically potent factor itself, corresponding to 'dynamical' aspects of perception that form a part of alive experience of the viewing process, but are lost in the 'static representation'. This noise becomes in turn a substrate for painting on a digital canvas, with tonality, colours, and shape patterns expressing various 'transitionary' esthetic experiences and mental states. (One of the original and thus rare effects, used especially in the Abstractions and Wilder Wein cycles, is based on processing a binary .jpg file with an initial photo through a converter of Polish 8-bit ASCII codepages.) With time I've started to put more and more emphasis on using complete crops of photos as globally defined layers (or, eventually, distinct parts) of the image, so that the local structures of the resulting graphics would have in principle larger inter-local cohesiveness. In Spiritual transformations cycle this constraint has helped to increase the integrity of formal substance and semiotic essence (reflections of light, literally and figuratively, from experiential μsamādhis). The short collection of the covers of Imaginary albums has more humoresque character, yet check out the (literal and metaphorical) layers of 'The Lwów Volta'.

  Texts & zines

  translations: The intention behind the translation style used here is to maximise the transmission of the original polyvalence of semiotic interconnections between particular wordings (i.e., their semiotic loci), constrained by the limitations of translator etc., at the expense of suboptimal translation of the structure of rythms and rhymes. This expresses the intuition that the latter reflect foremostly the structural properties of a particular language (thus, a large-scale global feature, providing a data type that is common to many users), while the specific choices of the semiotic interconnections represents more the individual soundscape of an author (so the rythms and rhymes characteristic to his individual data type are represented primarily in the relationships between meanings).
