* Also added gradual acceleration of the ball, shrinking of paddles, and
* scorekeeping.
*
+ * Modified by Gereon Steffens <gereon@steffens.org> to add -clock and -noise
+ * options. See http://www.burovormkrijgers.nl (ugly flash site,
+ * navigate to Portfolio/Browse/Misc/Pong Clock) for the hardware implementation
+ * that gave me the idea. In clock mode, the score reflects the current time, and
+ * the paddles simply stop moving when it's time for the other side to score. This
+ * means that the display is only updated a few seconds *after* the minute actually
+ * changes, but I think this fuzzyness fits well with the display, and since we're
+ * not displaying seconds, who cares. While I was at it, I added a -noise option
+ * to control the noisyness of the display.
