From http://www.lsionline.co.uk/news/story/1000-DHA-Digital-Light-Curtains/-BOX32C :

What is now DHA's DLC began its life as a prototype Light Curtain produced for the English National Opera's 1976 production of Dalibor and in 1978 24 Light Curtains were used in Evita to create the innovative production concept of a 'white out' effect. The first motorised Digital Light Curtains were installed on Miss Saigon in New York and the range is now available in six or eight lamp versions with integral tilt drive and colour scroller. DLCs offer reliable versatility, particularly when used with the optional pitching yoke which provides a second axis of movement.
