Finite field plotter (Alexander Ma)

This applet allows you to input a prime p, and then draw pictures of lines, circles and some other selected conics over the field with p elements.

The applet is the work of Alexander Ma, a graduate student in mathematics at UNSW in 2005.

How to use it:

Lines are drawn by holding the mouse over the plane to specify an initial point, and then moving it to a second point. Circles are drawn by starting with a center, and then finding a point on the circle. The coordinates of the current point are visible at all times. You may store different curves, using different shapes and colours.
