In the city of Delft in The Netherlands the SEKU school for teaching asked Lucien den Arend to do a pollard willow project in the gardens, in front of the main building. Wim Broer of the SEKU called Lucien den Arend and on the 11th of April 1988 the project was planted. Forty willow branches were planted in two squares. The outer square ten by ten trees and the inner one with just the corners marked. A day or two later the gardener removed the project because he could not mow 'his' lawn.
Ars longa vita brevis is in this case not the appropriate expression.
