Elastic Videology celebrates 20 years of some of the stars of our video world from the beginning of our collaboration in 1999 in art and in life showing a miscellanea catalog of stills, books, videos, video installations, video performances, and large-scale projects of public video art. This book you are about to enjoy is not just any catalog. It is an expanded catalog, on the net, which through the QRs connects and expands the catalog itself with the space of the web connections, with the use of video links and textual links that allow you to enter in depth and in multimedia mode, in the artistic universe and in the twenty-year artistic research of Elastic Group, in their MetaVideo World. This is an expanded catalog, in which the circularity of information and the flow of data are superimposed on the temporal sequence of the video image, because this catalog is conceived as a loop of video frames but also as a network of textual interconnections with the captions and QR codes. This is not a catalog, it is a Code.
