A Flickr user by the name of Endless Forms Most Beautiful included some of my photographs as his/her favorites so of course I had to go check out this person to see how nefarious their intentions are. Endless Forms says on their profile that "I'm using this as a place to collect interesting things for inspiration and teaching" and what a wonderful collection of images they have! This set, called Kunstformen, draves.org is from a series of 100 lithographs entitled "Kunstformen der Natur," German for "Artforms of Nature", created by Ernst Haeckel in 1899-1904. Here's just one example, that reminded me of something seen through an electron microscope. It's a fascinating set of images.
