Created by Doug Pfeffer, Hairrrr is a Mac application that converts images into fields of hair. A while back Doug posted some sample generated images that sort of looked like body hair on the Cinder forums. Although he still hasn't found a project to integrate it with, he touched it up a little bit and wrapped it up in an OS X application. You can load your own image (through that button or drag n' drop) and save the images out. Options include hair length, density and also ability to invert.
