PS Have put a photo of the Ryoan-ji rock garden (with its new cyprus-bark roofed wall ) up on http://megalithicpoems.blogspot.com/ Will leave it there for a day or so (unless I can find a poem to go with it :-)
Interesting, isn't it, that cultures so far removed from one another as those of Britain and Japan still find some sort of commonality in the ordered placing of stones.
