The gate which is shown in an exhibition setting here and with an art padlock by Manuel Guerra was built to go directly over the front entrance door of a German foreign aid worker in Ecuador. The poor guy had been robbed twentythree times. He was a former prize boxer and had taken to beat up burglers whenever he could catch them. The design was partly meant as a warning to these burglers, and partly it was inspired by the lines of an electromagnetic field in a transformer. The owner was also an engineer by profession.
