Speaker: mare In the last years, technology-savvy artists and technologists have taken over the art world with works addressing current societal and political issues. Their works are located at the intersection between art, technology and activism and are dealing with a variety of problems like free speech, freedom of movement, military and governmental power, corporate and governmental surveillance to name just a few. This talk will present relevant works in this field and will draw connections between critical art and regulatory power, warfare, surveillance, electronic waste, electronic self-defense and the re-appropriation of architectural and technological artifacts in militant ways.

In the latter part I am going to exemplify these concepts by showing important works in their fields, like artistic counter-survellance installations, passive reconnaissance walks through metropolitan cities, forensic analysis of HDDs discarded as electronic waste and so on. I will also show some of my personal works in this field, ranging from passive radio antenna stations towards universal modems to transform existing conductive architecture into a computer network. As a hybrid between computer scientist and media artist, I am creating works at the intersection of engineering, sculpture and formal aesthetics, which investigate power relations between citizens and technology, and often also the relations between citizens and the state. In my latest works, I am pondering how technology can be capable of re-democratizing public space, and how the issues surrounding the creation of private spaces through technological means can be artistically addressed.
