Éva T. Bortnyik and Csaba Tubák have been dealing in their works with the phenomenon "light" since the eighties. Beginning with traditional film-projections, later they turned to "expanded cinema", then - through video- and light-installations - they got to the present intermedial creations.



1 "The profile of Symmetry Symmetry profiled"

Moving an imaginary symmetry-axis, a two-dimensional symmetry-plane comes to existence. On both sides of this virtual symmetry-plane we can find a transparent imprint of the same composition. As a result one can experience different imprints ("profiles") of this double-picture composition, depending on the point or angle the picture is being looked at.

2 "Disturbed Symmetry"

With the help of two video projectors set up parallelly the same geometrical animation will be projected two times /partly overlapping/ onto a black screen, where the picture becomes colourless. A white horizontal cylinder is located in the center of the black background (Fig. 3). The two projected pictures differ from each other, since one of the projectors always shows the mirror-image of the animation. Consequently, the symmetry-axis runs vertical in the middle of the picture (Fig. 4, 5, 6).

The clear symmetry we get this way will be "disturbed" during the performance through the interference of the artist. For instance through the rotation of the white cylinder around its own axis, so that the picture appearing on its surface does not correspond to the otherwise symmetrical general view (Fig. 6). Also, the mirror image projection can be switched for normal during the performance, so that a parallel picture, without a symmetry axis is being created.
