Images from the sky at the moment of
dusk
and dawn are
constantly sent to a screen, where a central circular field of one sky
is superimposed on the other. Tracking over time around the earth the
light of the sky in the inner circle is changing complementary to the
light of the sky surrounding it.
The realisation is based on the SUNPENDULUM project by using its online image streams of the 12 Time-Eyes around the earth. With the earth rotation, that means over time, dusk-light and dawn-light can be tracked by selecting those 2 videocameras directed towards the dusk- and dawn skies respectively. WWW-based – Java program realisation by Herbert Schwabl, live image capture by Stephan Mantler in collaboration with the Sunpendulum team and the Sunpendulum partners around the earth. |
