Family tradition of igloo building in the yard was resurrected thanks to my geological engineer/exploration geologist daughter Évelyne and teacher/nurse Nick. Their original architecture of round igloo turned out to be too big, so they changed the design to 1/2 igloo.
The 1/2 igloo was completely destroyed by New Year's Day (January 1) due to rain and unseasonably warm weather in BUBAR (Broken Up Beyond All Repair) situation.
Potential Discovery or Invention
My engineer/mathematician/computer scientist son François has pointed out that the 1/2 igloo resembled the Toilet Museum building.
