December 1999 Pencil installed in the hedge of the Freud Museum, London. Entry to the museum is through a gate in this hedge, which I think is formed from the plant Buxus sempervirens.
July 2003 Installation in Lucerne, Switzerland. In the Middle Ages, Lucerne had four bridges (more than any other city in Europe) and a clock which every hour chimed one minute before every other clock in the city. I thought this could be evidence for an anti-gravity vortex but it turned out to be a dead end, the clock had been deliberately set that way.
October 2003 Installation made on the roadway near Circular Quay, Sydney, Australia. About half of Sydney Harbour has a depth of 9 metres or more at low water.
June 2004 The installation in the Jardin Botanique, Bayonne, France. The home of Roland Barthes for much of his adolescence, Bayonne is also known for the Jambon de Bayonne or Bayonne ham. Jambon de Bayonne was apparently discovered after a wild boar fell into local saline springs and was preserved by the salt.
