As I approached her web, I noticed the web start to vibrate back and forth in quite an exaggerated fashion. [...]

Amazing Neurons from Embryonic Stem Cells in a Dish
I grew these mouse embryonic stem cells on a plate, and through various molecular trickery, I made them turn in to the crazy cell types you see here. (Click for larger images)
Check out the next two images. They are the same cells viewed in two different ways (normal light, and epifluorescence).
Long neuronal axons stretch [...]

Note the broken hourglass on the female below.
