Knitter's Anatomy

For those of you who are not familiar with the online world of knitters, you may be interested to know that a subset of these strange creatures are quite nerdy (in a scientific kinda way).

Allow me to present to you "Knitter's Anatomy":  a smattering of knitted human organs that can be found around the Interwebs.  I don't think I need to expound their awesomeness.  Just know that I am reveling in it as well.

Exhibit 1:  The uterus.  (found here)

Exhibit 2:  The vulva.  (found here)

Exhibit 3:  The gastrointestinal tract.  (found here)

Exhibit 4:  The brain.  (found here)

Exhibit 5:  The heart.  (found here)

Exhibit 6:  The lungs?  (found here)

Well, there you have it, folks.  Maybe I'll try for an anatomically correct version of the lungs, in a boucle yarn to simulate the alveoli (Karli's idea).  Or perhaps a pair of kidneys, in a nice burgundy mercerized cotton, ureters in a goldenrod yellow and the bladder in a pastel pink.  Oh, the possibilities....
