Petrus Plancius (Pieter Platevoet, 1552-1622) was a famous Flemish cartographer. He included new constellations in the austral celestial emisphere. In 1612, he drew 12 gores for a 14.5 cm diameter celestial globe, with eight new constellations inspired to the Bible. For the present model, the original gores published in 1649, were downloaded from the Bibliothèque nationale de France website. The colours of the original file were digitally converted in the “nocturnal” version here presented.

Petrus Plancius (Pieter Platevoet, 1552-1622) fu un famoso cartografo fiammingo. Autore di numerosi globi celesti, egli introdusse nuove costellazioni nell’emisfero australe. Nel 1612 disegnò 12 fusi per un piccolo globo celeste del diametro di 14.5 cm, in cui compaiono otto nuove costellazioni ispirate alla Bibbia. Per questo modello, i fusi originali, pubblicati nel 1649, sono quelli scaricabili dal sito web della Bibliothèque nationale de France. Con un semplice processo di ridefinizione della gamma cromatica, i fusi sono stati trasformati nella versione “notturna” qui proposta.

Giovanni Maria Cassini (1745 – 1824) fu un costruttore di globi, geografo, incisore e cartografo italiano. La sua opera principale fu il Nuovo Atlante Geografico Universale del 1792-1801. Nel 1790 la Calcografia Camerale di Roma pubblicò I suoi dodici fusi per globo terrestre, aggiornato secondo le ultime rilevazioni effettuate durante I tre viaggi attorno al mondo del Capitano inglese 
From 5 to 28 April 2011 I will be on board of the German research ressel METEOR for a transMediterranean cruise. The principal scientific objective of the cruise (code M84/3) has two closely-linked components: understanding and documenting the large-scale Mediterranean water property distributions, their changes and drivers of those changes, and addressing questions of a future Mediterranean Sea that will increase in dissolved inorganic carbon, might become more stratified and experience changes in circulation and ventilation processes due to global warming.

When the double cone is placed at the lower end of the frame, it automatically starts to roll upward, giving the impression of defying the universal law of gravitational force. Because of this phenomenon, astonishing in its seeming contradiction of common sense, the apparatus was often described as a “mechanical paradox.” [for more information, visit 
Released on 2nd February 2006, WitS is my biggest and the most complex paper automaton I ever designed.
On 16 September 2005, the automaton Sweet Dreams was launched on the web. At that time, it was considered the first paper automaton employing the mechanism called Geneva stop. 
The Geneva stop (or Geneva drive) is a mechanism that translates a continuous rotation into an intermittent rotary motion. It is an intermittent gear where the drive wheel has a pin that reaches into a slot of the driven wheel and thereby advances it by one step. The drive wheel also has a raised circular blocking disc that locks the driven wheel in position between steps. The name derives from the device’s earliest application in mechanical watches, Switzerland and Geneva being an important center of watchmaking. One application of the Geneva drive is in movie projectors: the film does not run continuously through the projector. Instead, the film is advanced frame by frame, each frame standing still in front of the lens of 1/24th of a second. (from 
This is a study for a life-size model that maybe in the future I will build. It measures mm 300x221x408. The 3D model was prepared after re-topologization of a model downloaded from the “INRIA Gamma team research database Website Collections”
