Joost RekveldA sidetrack from today; this is one page from the "Sekka Zusetsu" (雪華図説), a collection of 86 drawings of snowflakes made in 1832 by Doi Toshitsura, a local Japanese ruler. He collected snowflakes on a black cloth and observed them under a microscope that had been imported from The Netherlands. Apparently these drawings triggered the development of hexagonal ornaments in Japan.
