We're absolutely blown away by the work of Sarah Yakawonis, a Maine-based artist who uses a technique known as quilling to create intricate anatomical models like the ones you see here. The meticulously positioned strips of coiled paper look so much like the folds of a brain, or the sinewy striations of human muscle, I actually felt a bit queasy looking through examples of her work during lunch.

We've featured a few examples of Yakawonis' work below, but you'll find tons more (including a variety of non-anatomical pieces) on etsy, Society6, and All Things Paper . [Via COLOSSAL]
