I spent 15 minutes looking for a car I've seen at a car show (Eyes on Design) which would have been nice to post right about now.
The car is a hand made replica of a one-off aerodynamic car made in he mid-1920's. I spoke with the builder/owner, located in Indiana (I think).
Anyway, the way the shape was achieved was steel plate cutouts were made matching the windshield and radiator shape and areas.
A blower or wind machine of some kind placed in front, and clump fulls of sand were tosses into the airflow. The sand would hit the steel plates and deflect/move around the plates/objects. The pattern of this sand migration/movement was recorded somehow and replicated to form the aluminum body.
If or when I ever find my pictures, I'll post them. This same car was on Hemming's or some other site within the last 9 months as a feature.
