+Draws quasiperiodic tilings; think of the implications on modern
+formica technology. Written by Timo Korvola.
+
+In April 1997, Sir Roger Penrose, a British math professor who has
+worked with Stephen Hawking on such topics as relativity, black
+holes, and whether time has a beginning, filed a
+copyright-infringement lawsuit against the Kimberly-Clark
+Corporation, which Penrose said copied a pattern he created (a
+pattern demonstrating that ``a nonrepeating pattern could exist in
+nature'') for its Kleenex quilted toilet paper. Penrose said he
+doesn't like litigation but, ``When it comes to the population of
+Great Britain being invited by a multinational to wipe their bottoms
+on what appears to be the work of a Knight of the Realm, then a last
+stand must be taken.''
+
+As reported by News of the Weird #491, 4-jul-1997.
