 Info about Java
 The Geometry Center
 Until 1998, the Geometry Center was located at the University
of Minnesota. It is now closed, but its web pages still exist. The program
JGV (Java GeomView) was developed at the Geometry Center.
 Present web address of the Geomnetry Center:

 Example of the HTML code that calls the java applet "JGVApplet":
 Various interactive sketches of algebraic surfaces
 Quadric ruled surfaces:

Quadric cone
 Smooth quadric surfaces:
 Each of the smooth ruled quadrics contains two families
of straight lines . . .
 Other algebraic surfaces:
 The Cayley surface is the projective dual of the Steiner surface.
(Unfortunately, I haven't yet made a good interactive picture of it.)
 The following site contains some nice static pictures of the Cayley surface:
