Thank you Brian for the name of the process, David for a fascinating
avenue to explore, and Lloyd and Mitch for references.
A google for Satsuo Ando found a reference to my teacher in
Adelaide, Wonho Chong, who was once a student of Satsuo Ando; along
with a look into the beautiful work by Steve Midgett. I spent the
afternoon reading and reminiscing, ordering a book, and looking at a
change in creative direction.
