Take a look at the Elliptical Profile Generator, (including Source) There are more interesting applets on Jens Trapp's Java Page
The shape of the Naca 4 Digit profiles is determined by three parameters, the camber (first digit), the position of the camber (second digit) and the thickness in percent (two digits). Profiles without a camber are symmetrical. Those symmetrical profiles are often used as keel in shipbuilding or modeling. The tool requires Java.
