"In two time zones, exactly 12 hours apart, videocameras are directed towards the sky and connected online to the Internet. Two videocameras – time-eyes – watch the sky in parallels. The images from both time-eyes are constantly sent to a screen, where a central circular field of one sky is superimposed on the other. With the rotation of the earth, that means over time, the light of the sky in the inner circle is changing complementary to the light of the sky surrounding it, 12 hours distant. Two moons circulate around this field and their position shows the local time, simultaneously correct for both time zones" . 

Hofstetter Kurt released this concept of the complementary light pendulum clockwork in 1993. A media art installation of the 1st clockwork was temporary realized at the echoraum Vienna in 1999 using the software by Stephan Mantler / imagination gmbh. 

In 2003 the www-client of the complementary light pendulum clockwork was released as a Sunpendulum parallel project using the images of the Sunpendulum Time-Eyes and made permanently available to the public. (note: temporary offline periods produce black images)
