BG, I had an experience in '92 that taught me something about the Japanese perspective on the role of the viewer's imagination. You may find it of interest.
The headliner at ABS '92 in Hershey, PA, was Susumu Sudo. Besides his bonsai talks and demos, he gave one presentation on suiseki. (All thru an interpreter.)
He took an irregular green stone, about the size of a small cantalope, and set it in a tray of sand. Then he asked us what we saw.
Many thought it looked like a mountain; others an island. (I frankly thought it looked like a frog. Other Americans laughed, but Sudo-san did not.)
Then he took a small model boat, about as long as a woman's finger, and set it on the sand near the stone. What he said next caught me by surprise. An American would have said something like, "Now I've given you more to go on." But Sudo said something else.
"Now I have restricted your imaginations."
Treebeard,
This is a good insight and I never thought of it that way. Thanks.
