Vector Hack is the biannual international festival devoted to experimental analogue vector graphics. The first edition was in 2018. in Zagreb and Ljubljana. The second edition took place in Rijeka, Ljubljana and Dubrovnik in 2020. Experimental vector graphics artists use lasers, analog oscilloscopes, old video game consoles, mechanical drawing machines, and other equipment to produce images using an X, Y, and Z coordinate system. They often feed these display devices with elaborate handmade electronic synthesizers, complex custom-made software, or other experimental instruments of their own design. The resultant images are often sinuous, intensely energetic, and radically different from what is possible on a digital screen! Vector Hack gathers artists, researchers, developers, and performers from around the world as well as from the strong regional scene of Italy, Austria and Croatia. A unique combination of community meeting, conference, and international arts festival brings together practitioners in the field of laser and oscilloscope art for talks, workshops and live performances. It is a chance to experience audiovisual works which employ unusual, analog, and sometimes obsolete display technologies, and to bathe your eyes in a different kind of light. It is conceived and initiated by Ivan Marušić Klif and Derek Holzer with assistance from Chris King.
