sundials nocturlabes and motors

Sundials : I love this french blog http://pagesperso-orange.fr/cadrans.solaires/cadrans/cadran-jean-michel-ansel.html about sundials around the world. There are english subtitles too. I was also very taken with his trip to a sundial park in Britanny and had no idea there were such things as sundial parks: http://pagesperso-orange.fr/cadrans.solaires/cadrans/originaux-parcs-france.html

I am going to make a nocturlabe next as I had not previously come across them and want to try one out next time there is a clear sky
