Here is a sculpture called Grub by Aaron Kramer. It is made of used coffee stirrers (top) and used bristles from street sweeping brushes (bottom) woven on a steel armature. I was particularly interested in this work because I have been collecting bristles from street sweeping brushes that have come loose and scattered on the street. Aaron gets his bristles from a company who replace the bristles on worn out brushes.
Here is some of his work on the Packer Schopf Gallery website.
Here is his own website.
