yeah, and if you have a good sorted vertices for those polygons, you can write a script that let them wave by moving the vertices from layer to layer just for a bit. like all vertices in layer 1 (on the bottom) moves for 1, the layer abour vor 1.5, the layer above for 2, and so on. and let it swing around, maybe even depending on the fly direction so the hairs get pressure from wind. its a greatz effect, just a bit "hairy" (8D) to script.
