Voir sur FrenchStream. A 12 minute film about the Evoluon [a conference centre and former science museum erected by the electronics and electrical company Philips at Eindhoven in the Netherlands], of which is thought that it was made in 1969 by Bert Haanstra or Pim Heytman. British TV viewers will probably remember this movie, since the BBC used it for test transmissions. In those transmissions a number of films was broadcast every day in the early seventies so technicians could adjust the new color TVs they installed at customers homes. —http://www.dse.nl/~evoluon/film-e.htm
