– a sphere of interaction to interfere with complementary light & time online
The installation is based on the sky as the medium for the light of the sun - the time - as well as on the
rotation of the earth moving the light of the sun in a continuous circulation of light and shade, day and
night in parallels.
Online sky images from one time zone on earth are projected onto one side of a white balloon
(diameter approx. 1,5m) hanging like a sphere in the center of a darkened space. At the same time
vica versa sky images from the complementary time zone (i.e. 12 hours apart) are projected onto the
opposite site of the balloon. This balloon, exactly placed in between the two projectors facing each
other, eclipses both projections. Thus, the shadow of the balloon creates a black hole in both sky
images, right there where the light source of the projections originates. In the surrounding space of the
balloon the light of the sky interferes with its complementary one and with people moving around
embedded in a cosmic sound silence.
People are able to select online and interactively the sky of 12 different time zones around the earth and vica versa its complementary ones to be projected on the balloon. Going around the earth one’s finger triggers morphing light interferences of parallel skies from complementary time-zones live.
The realisation is based on the Sunpendulum project using the online sky image streams from the 12
Sunpendulum Time-Eyes – i.e. video cameras installed at Universities watching the sky in 12 timezones
around the earth:
( 1 ) University of Hawaii / Maui Community College / USA
( 2 ) Universidad Autonomous de Baja California Unidad Ensenada / MX
( 3 ) University of New Orleans / USA
( 4 ) Bermuda Underwater Exploration Institute / GB
( 5 ) Universidade dos Acores / Angra Campus / P
( 6 ) Universidad de Granada / E
( 7 ) Ain Shams University Cairo / EG
( 8 ) Zayed University Dubai / UAE
( 9 ) Jadavpur University Kolkata / IND
(10) Hong Kong University of Science and Technology / PRC
(11) Tokyo Kanazawa Institute of Technology / JP
(12) College of the Marshall Islands / RMI
The WWW-based - program was developed by Herbert Schwabl, Flash program developed by Claudia
& Peter Stieglecker, Live image capture and system administration by Marcus Priesch in cooperation
with the Sunpendulum team and close collaboration with the Sunpendulum partners and support
around the earth.
