We have written a Java applet to illustrate the meaning of curved geometry.
The applet provides a mapping interface similar to MapQuest or Google Maps;
features include the ability to navigate through a space and place permanent
point objects and/or shapes at arbitrary positions. The underlying
two-dimensional space has a constant, positive curvature, which causes the
apparent paths and shapes of the objects in the map to appear distorted in ways
that change as you view them from different relative angles and distances.Comment: 4 page
