The kinetic site-specific installation is a space-time triangle whose outer points are defined by a triple of the forgotten historical Karlín factory chimneys. It is in the Corso Court area, in the courtyard on Karlín Square 4 and in the Pernerova 55 industrial area. The installation consists of three light arms in symbolic national colours, which are located on the tops of the chimneys. Each of them rotates at a different speed. The arm in the Corsa Court area is red and rotates as the hand for seconds, the arm in the yard of Karlin Square is blue and symbolizes the torque of the minute hand, the arm in Pernerova Street is coloured white and corresponds to the hour hand. Just as the physical space can be grasped by walking, which is often accompanied by the change of angles of view, which helps the one to get a whole orientation and contextual grasp of a given place on a larger scale, the temporal orientation in the imaginary Karlin triangle makes sense, like a result of the sums of these three light-visual information, up to the way from the church of St. Cyril and Methodius to the Invalides.
