* The movie people distribute their own Windows/Mac screensaver that does

- * Windows/Mac version at http://www.whatisthematrix.com/) doesn't match my
- * memory of what the screens in the movie looked like, so my `xmatrix'
- * does things differently.
+ * Windows/Mac version at http://www.whatisthematrix.com/) doesn't match

+ * things differently.
+ *
+ * See also my `glmatrix' program, which does a 3D rendering of the similar
+ * effect that appeared in the title sequence of the movies.

*
* ==========================================================
* washed out. They also definitely scrolled a
* character at a time, not a pixel at a time.
*
- * ==========================================================
- *
- * One thing I would like to add (to "-trace" mode) is an intro like at the
- * beginning of the movie, where it printed
- *
- * Call trans opt: received. 2-19-98 13:24:18 REC:Log>_
- *
- * then cleared, then
- *
- * Trace program: running_
- *
- * then did the trace.
+ * And keep in mind that this program emulates the
+ * behavior of the computer screens that were visible
+ * in the movies -- not the behavior of the effects in
+ * the title sequences. "GLMatrix" does that.
*
- * I was also thinking of sometimes making the screen go blank and say
- * "Knock, knock."
+ * ==========================================================
*
- * However, the problem with both of these ideas is, I made the number images
- * by tooling around in GIMP until I got something that looked good (blurring
- * and unblurring and enlarging and shrinking and blurring some more...) and I
- * couldn't reproduce it if my life depended on it. And to add anything other
- * than roman digits/katakana, I'd need to matrixify a whole font...
