Hektor is impressive both because of its technical implementation as well as its fantastically simple concept. I want Hektor. Hektor is a Graffiti Output Device. It was realized during two months in Summer 2002 by Jürg Lehni and Uli Franke, an electronics engineer from Zurich, for Lehni's diploma project at the école cantonale d'art de Lausanne (écal). Basically, this is a portable, very large scale, scalable printer. It can be attached to walls and controlled by software to spray shapes, text or anything else you want on any given flat vertical surface (i.e. a wall). I am completely awe struck by how wondefully cool this is.
