OK, last one from me tonight. In 2006 Alexander Mcqueen’s ready-to-wear show finished off with a damn near historic (pun, collection related) finale. Inside of the pyramid a ghostly figure materialized, only for it to be Kate Moss! The effect is created with plates of glass, which form the pyramid, and lighting techniques. The ghost was prerecorded and projected forth. Thanks toWikipedia, the effect is called Pepper’s Ghost.
