A Sundial for a North Wall

Detailed account of creating an outdoor reflection sundial over five years for a north-facing wall, using a mirror to project a sunspot. The final brass design is a hybrid, using virtual gnomon hour lines for GMT and analemmas marked by planets and asteroids for clock time correction, also celebrating the birth of grandchildren.
