This applet will compute the 2D Voronoi diagram of a set of points in the plane defined by the user's mouse clicks. It uses an algorithm that I've developed during my sabbatical.

(Insert stuff about Voronoi diagrams here and the general idea of the algorithm.)

If you find any bugs, let me know. Also, I'm still in the process of adding features to the program. Finally, there's a paper in the works to explain the algorithm parameters. The Help Tab gives a general idea of how to choose them, but may not be entirely clear.
