* 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.
+ *
+ *
+ * ==========================================================
+ *
+ * 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.
+ *
+ * ==========================================================
+ *
+ * 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.
+ *
+ * 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...
