Hello Friends...
The NASS website has posted a link to Dale M. Greer's fascinating
model of a monumental shadow plane dial for Reykjavik.

click on Sundial for Reykjavik
If you click on the images, you can see movies of the sundial in action.
If you click on Sundials at the page bottom, you can read a little
more about Greer's sundials, dating back to 1994, before most of us
had ever heard of shadow plane sundials.
Thanks to Bob Terwilliger for posting this.
Best wishes,
Mac
