sunpendulum home 
Since 1991 the artistic work of Hofstetter Kurt has focussed on parallelism and circulation, sky, light and time resulting in media art installations like “Im Augenblick” (Vienna, 1992), internet sculptures like “The Complementary Light Pendulum” (in progress since 1994) and “moving moments@pendel” (Vienna 1996) leading to the project Sunpendulum. In 1997 Hofstetter Kurt released the concept of the Sunpendulum project. With public and private support he was able to start with the realisation in 1998. From its nature the realisation is based on interdisciplinary cooperation in Arts and Science as well as on the assistance of a whole host of people and close collaboration with partners around the earth.  
The steps towards realisation have been accompanied by a PARALLEL MEDIA project – a parallel process of presentation, documentation and reflection by Barbara Doser and Hofstetter Kurt. Parallel artistic works reflect central topics like parallelism and circulation, light and shade and time. Along with the media of Video, CD-Rom, Photography, Print, Mixed-techniques it has been the InterNet in particular which has been playing a key role in mediation – 

INPLUSION --- realized August 2006 

In 1998 the Institute of Computer Graphics and Algorithms at the Vienna University of Technology, directed by Prof. Werner Purgathofer, was able to start with the software development for transmitting moving pictures from the 12 time zones via the InterNet, supervised by A.o. Prof. Michael Gervautz and processed by Stephan Mantler. The research process of all the necessary realisation-parameters has shown that all moving pictures of the sky have a very high coherence. Colour and form change very slowly. Thus, a high data compressionrate in the digital image process makes a transmission of moving pictures via the InterNet possible and, with a slight delay, the continous and synchronous broadcasting of the pictures from the 12 time zones to the 12 screens can be guaranteed.  
In 1999 the first Sunpendulum Time-Eye was installed on Maui/Hawaii. With this first research collaboration a software evaluation process was begun, coordinated by Christoph Traxler. It has come about that the main realisation item of INPLUSION is to install the Time-Eyes for permanent use in close collaboration with Universities or Research Centers in the respective time zones, which can easily provide all the necessary facilities in a very solid way. In 1999 the Time-Eyes of Bermuda, Granada, in 2000 the Time-Eyes of Cairo, New Orleans, Ensenada, in 2001 the Time-Eye of the Azores, in 2002 the Time-Eye of Dubai, in 2003 the Time-Eye of Hong Kong, in 2004 the Time-Eye of Kolkata, in 2005 the Time-Eye of Tokyo and finally in 2006 the Time-Eye of the Marshall Islands were installed.   
With support of the Austrian Mission in the respective time zones and on the occasion of a Time-Eye‘s installation, the collaboration partner has organized a big press event to communicate the participation and cooperation in the international Sunpendulum project. It has been a strong public relation communicating the Sunpendulum idea and concept around the earth. In 2002 the first public access to the Sunpendulum Time-Eyes was opened via the WWW-client of the parallel project ‘facing time eyes’ . In 2004 the WWW-client of the 'complementary light pendula' project was released as a Sunpendulum parallel project using still images online from the Time-Eyes. 

EXPLOSION --- ongoing realisation 

In 1998 the realisation was started to design a pavilion in public space for the circle of the 12 Time-Screens, where the continuous circulation of day and night can be strongly experienced in parallels at the same time.  
In close cooperation with the architect Reinhard Haslwanter a special pavilion – pavilion #1 – was  designed following the Sunpendulum vision of Hofstetter Kurt.  
In 2001regarding the realisation process in the respective time zones Hofstetter Kurt had to adjust his vision towards new realisation items and created the design for pavilion #2. Both pavilion designs fulfill the basic premise – having the pavilion open in all directions with no direct sunbeam reaching the inner circle of the screens – and being easily constructed, conforming to the principle of the "Golden Section" in a very fascinating way.  
In 2001 during the artistic work on the basic geometry of pavilion #2 a previously unkown construction of the Golden Section using the simplest means was discovered and resulted in a scientific paper publication 
In 2002 a model of pavilion #2 (scale 1:20) was created for international presentations and exhibitions and in 2003 the earlier idea of a temporary pavilion has been redefined in concrete terms as a permanent station - "the Sunpendulum Station Phi"
