* 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
+ * what the computer screens in the movie looked like, so my `xmatrix' does
+ * 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.
+ *
+ *
+ * ==========================================================
+ *
+ * NOTE:
+ *
+ * People just love to hack on this one. I get sent
+ * patches to this all the time saying, ``here, I made
+ * it better!'' Mostly this hasn't been true.
+ *
+ * If you've made changes to xmatrix, when you send me
+ * your patch, please explain, in English, both *what*
+ * your changes are, and *why* you think those changes
+ * make this screensaver behave more like the displays
+ * in the movie did. I'd rather not have to read your
+ * diffs to try and figure that out for myself...
+ *
+ * In particular, note that the characters in the movie
+ * were, in fact, low resolution and somewhat blurry/
+ * washed out. They also definitely scrolled a
+ * character at a time, not a pixel at a time.
+ *
+ * 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.
