Tim Hunkin who used to do the Rudiments of Wisdom cartoons in the Observer for many years and made lots of inventive tv programmes about how machines worked called "The Secret Life of Machines" and now makes wonderful automata for his own amusement arcade on Southwold Pier in Suffolk. A lovely man and very entertaining. Archie had a day off school especially to see him and got his autograph. Archie particularly enjoyed his animations made from photographs - a kind of 3-D version of those Monty Python catoons by Terry Gilliam. After the lecture Archie and I went to the Manchester Museum to see the newly installed T.Rex skeleton (a plastic copy) which was impressive and looked at the live exhibits which include Axolotls, poisonous blue frogs, snakes and monkeytoads? A very tiring day and I can see why Hazel collapses in a heap when she gets home after a full day of fending off students questions and commuting on the terribly uncomfortable and unreliable trains!
