Hektor is a portable Spray-paint Output Device for laptop computers created by designer Jürg Lehni and engineer Uli Franke.

"Hektor’s light and fragile installation consists only of two motors, toothed belts and a can holder that handles regular spray cans. The can is moved along drawing paths just as the human hand or old plotters would.

Hektor was created with a certain attitude towards design and the use of tools. Intuition played an important role in the search for a new output device that goes beyond the limitations of today’s clean computer, screen and vector-graphic based design and conveys the abstract geometries contained in these graphics in a different way than normal printers do.

The aim was to make a statement about design by providing a new tool to other designers and artists to experiment with, a tool with an inherently particular and distinctive aesthetic."
