Here's what you can do:

Click in the white area to add points. You can also drag a point around by holding down the mouse button. For now, you can only do this immediately after entering a point (you can't select one and drag it yet).

The red dot is the bivariate mean of the points (if you have entered more than one).

The green dot is the Convex Hull Peeling median (if you have entered more than three points). If red and green coincide, red wins.

All other colors represent points that were peeled in parallel.

Use netscape navigator if possible, cause for some reason, the reset button doesn't even appear on netscape communicator for me.
