GPS Drawing

GPS Drawing combines art, travelling (walking, flying, and driving) and technology and is a method of drawing that uses GPS to create large-scale artwork. Global Positioning System receivers determine one’s position on the surface of the Earth by trilateration of microwave signals from satellites orbiting at an altitude of 20,200 km. Tracks of a journey can automatically be recorded into the GPS receiver’s memory and can be downloaded onto a computer as a basis for drawing, sculpture or animation. This journey may be on the surface (e.g. walking) or taken in 3D (e.g. while flying).

The idea was first implemented by artists Hugh Pryor and Jeremy Wood, who have drawn a 13-mile wide fish in Oxfordshire and spiders whose legs reach across cities. They have also provided an answer to the question ‘What is the world’s biggest ‘IF’? It happens to be a pair of letters, ‘I,’ which goes from Iffley in Oxford to Southampton and back, and ‘F” which traverses through the Ifield Road in London down to Iford in East Sussex, through Iford and back up through Ifold in West Sussex. The total length is 537 km, and the height of the drawing in typographic units is 319,334,400 points.

Paperclip

one red paperclip

A paperclip is an instrument used to hold sheets of paper together, usually made of steel wire bent to a looped shape. Most paper clips are variations of the Gem type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire. Common to paper clips proper is their utilization of torsion and elasticity in the wire, and friction between wire and paper.

When a moderate number of sheets are inserted between the two ‘tongues’ of the clip, the tongues will be forced apart and cause torsion in the bend of the wire to grip the sheets together. Too many sheets will cause the elastic limit of the material to be exceeded, resulting in permanent deformation. Paper clips usually have an oblong shape with straight sides, but may also be triangular or circular, or have more elaborate shapes. The most common material is steel, but molded plastic is also used. Some other kinds of paper clip use a two-piece clamping system. Recent innovations include multi-colored plastic-coated paper clips and spring-fastened binder clips.

PAL-V

pal-v

PAL-V Europe is a Dutch company who are developing a flying car, the PAL-V One, an autogyro or gyrocopter, with a pusher propeller at the rear of the fuselage providing forward thrust and a free-spinning rotor providing lift. Directional stability is provided by twin boom-mounted tailfins.

It has a tricycle undercarriage with relatively large wheels. On the ground, the propeller and rotor are stopped and power is diverted to the wheels, allowing it to travel as a three-wheeled car. Unusually, it leans into turns like a motorcycle, a solution pioneered by the Carver vehicle, also produced by a Dutch company.
