Truth is Concrete was a 24/7 marathon camp in Graz (September 21–28, 2012) focused on artistic strategies in politics and political strategies in art. I contributed two network maps and presented a talk, “Network as a Medium of Critique and Action,” on September 25 at 8 pm in the Black Cube.

Collaboration Network

Participants were asked to list other attendees they had previously worked with. These lists were combined into a collaboration network of 186 names linked by 1,030 connections. Each name’s size reflects its “betweenness centrality,” a measure of how often a node acts as a bridge within the network. Clusters of related participants are color-coded, showing sub-networks or communities. By running a software simulation, names naturally repositioned themselves through connecting forces, revealing central figures, hidden links, tight clusters, structural holes, and outliers.

Tactic Similarity Network

Attendees also listed the tactics they use in their practices, resulting in a network of 749 unique tactics connected by shared use. As with the collaboration network, each tactic’s size is determined by its betweenness centrality. A software simulation again arranged the nodes, exposing major tactics, indirect links, distinct clusters, structural gaps, and outliers.
