The largest egg mosaic consisted of 66,000 coloured eggs and was created by Société de Développement des Intérêts d'Ouchy (Switzerland) at Place de la Navigation in Lausanne, Switzerland, on 2 April 2010. Over 100 volunteers took part in assembling the mosaic, which consisted of 19 different colours of dyed eggs. Proceeds benefited families with children suffering from cancer.
