Der Niederländer Theo Jansen baut aus einfachen Plastik-Isolierrohren komplexe Gebilde mit einer kompizierten Bewegungs-Mechanik: die sogenannten Strandbiester. Sie laufen, nur angetrieben vom Wind, wie organische Wesen über den Strand.
Seit 1990 arbeitet Jansen, ein studierter Physiker, am Konzept dieser technischen "Organismen". Er hat unterschiedliche Typen ("Spezies") entwickelt, die wie die Skelette urzeitlicher Riesenwesen anmuten. Seine ständigen Verbesserungen und Entwicklungen folgen dabei einem evolutionären Prinzip. Die Bewegungen der Gebilde muten organisch - fast lebendig - an. Ohne spezielle Antriebe bewegen sie sich allein durch die Kraft des Windes und eine ausgetüfftelte Kinematik.
Faszinierend ist die Gleichzeitigkeit von Komplexität der Kinematik und Einfachheit der Grundelemente aus denen die "Strandbeester" bestehen: Plastikrohre und Kabelbinder.
