On precisely noon of June 21, 1980, on the summer solstice near Canada’s most northerly inhabited village of Grise Fiord, Ellesmere Island. I placed stones, one after the other, at the end of the shadow cast by the previous stone. The outdoor installation was entitled Stone Time Line (1980, photo-documentary piece, 1994). The EEG tracing was done while I thought Creative Thoughts (1980). The musical score applied to this piece was from Igor Stravinsky’s Tango.
