Falmaidan (which in the Elventongue Sindarin means "maker of waves") is a program
for realistically simulating the movement of fluids. It works as a preprocessor for POV-Ray scene files. The aim is to produce breathtaking animations one day.
Similar to Robert Lang's TreeMaker software, this program will figure out how to fold a square piece of paper such that the inputted shape can be cut with just one cut. See http://theory.lcs.mit.edu/~edemaine/foldcut/ for details.
