The three-dimensional spacetime diagrams below are used as examples in a recent paper. Clicking on each image will take you to a page containing that image as a rotatable Java applet.
(We are working to improve the quality of these applets. Comments welcome.)

Read the full paper here for a more complete discussion of each diagram. These figures were originally drawn using Mathematica, then converted to Java applets using JavaView.
