  32 Quasiperiodic tilings.
  33
  34 In April 1997, Sir Roger Penrose, a British math professor who has
  35 worked with Stephen Hawking on such topics as relativity, black
  36 holes, and whether time has a beginning, filed a
  37 copyright-infringement lawsuit against the Kimberly-Clark
  38 Corporation, which Penrose said copied a pattern he created (a
  39 pattern demonstrating that "a nonrepeating pattern could exist in
  40 nature") for its Kleenex quilted toilet paper.  Penrose said he
  41 doesn't like litigation but, "When it comes to the population of
  42 Great Britain being invited by a multinational to wipe their bottoms
  43 on what appears to be the work of a Knight of the Realm, then a last
  44 stand must be taken."
