Nature can be a great inspiration, a jumping off point for furniture designers. One example can be seen in this shelf by designer Floris Wubben. The shelf is a juxtaposition of the strong, solid, and earthy tree forming the side of the shelf, and the light and airy white web-like material forming the shelves. So what's the inspiration behind the shelf?
A tree fungus.
