Hülle aus Papier

Man kann eine Hülle um eine Punktlichtquelle bauen, die keinen Schatten wirft und doch in gewisser Weise dick ist. Da aber eine Glühbirne keine exakte Punktlichtquelle ist, und beim Zuschnitt des Papiers kleinere Abweichungen von der Idealform fast nicht zu vermeiden sind, wird das Ergebnis unscharf. Das Papier schlägt Wellen und es entstehen interessante Schatten mit eigener Dynamik.
