Installations are at the service of the explorer who has to orient himself in order to find what he doesn’t know and has never seen. There are combinations, like in chess, that have never been observed nor tried out; like in music, where notes have never been heard together in this particular rhythm. Or in words, in colours. The physisists and mathematicians have never tried this unknown formula that they long for and that will open their minds to yet other possibilities. In all diciplines there are new directions to discover, new roads to take.
