I visited the Harvard Museum of Natural History today, and one of their current exhibits is Glass Flowers, a truly astounding collection of glass plant models created by Leopold and Rudolph Blaschka from 1886 to 1936. They created nearly 4,400 models by hand out of glass with wire reinforcement. I could barely wrap my head around the time and skill that went into the collection. The models range across plant families and feature both actual size models as well as larger anatomical pieces.
If you live in the Boston area, definitely check out the museum and this exhibit.
