His Blinky Palermo constructive pictures have remained in my memory because they particularly appeal to me, because I can't produce such a thing. I always found it very good how he made it and that he made it – this astonished me. There was an aesthetic quality which I loved and which I couldn't produce, but I was happy that such a thing existed in the world. In comparison, my own things seemed to me somewhat destructive, without this beautiful clarity.
