Norbert Heins, on behalf of the WEISS-Kunstbewegung in Berlin, invited me to conduct my incavation project, first conceived a decade ago, as part of the WEISS-HERBST-KOLLEKTION 2001. He made it all possible. Sabine Reinhold, who had been present when the idea was born orginally, assisted enormously during the practical work on 4-5 September 2001. Tom had to spend two days without his dad so early in his life. Thanks to them all.
