Sunpendulum is an art, science and technology project devised by Austrian media artist Kurt Hofstetter.
Twelve video cameras called "time-eyes" are connected to the internet in twelve locations in twelve time zones around the Earth, observing the sky twenty four hours per day, continuously creating a hypothetical "sun clock" which spans the planet.
The installations were located in:
The kernel team consists of scientists (chiefly from the Institute of Computer Graphics and Algorithms at the Vienna University of Technology) and artists. Its primary tasks are ongoing technical developments which maintain the integrity of the project and its hardware and software.
The collaboration partners are scientific and academic institutions which host the time-eye cameras, hardware and servers and participate in the project's international cross-cultural cooperation.
