Book excerpt: Interactive art organizes itself as an open system: it preserves its coherence by exchanging matter, energy, and information with the environment. In that manner, interactive art is art whose state of rest must be disturbed before it can become art at all. Yet, it is precisely this instability makes it ever more complex. Feelings are Always Local is published on the occasion of DEAF04, the Dutch Electronic Arts Festival, which focuses on interactivity as open system and interactivity in open systems. It features projects with a social and political slant, as well as projects that have a technological or biological character. Also included are essays, interviews and projects by DEAF04 international theorists and artists.
