Welcome to popular Wiki of the Day where we read the summary of a popular Wikipedia page every day.

With 245,311 views on Thursday, 6 January 2022 our article of the day is Pepper's ghost.

Pepper's ghost is an illusion technique used in the theatre, cinema, amusement parks, museums, television, and concerts.

It is named after the English scientist John Henry Pepper (1821–1900) who began popularising the effect with a theatre demonstration in 1862. This launched an international vogue for ghost-themed plays, which used this novel stage effect, during the 1860s and subsequent decades.

The illusion is widely used for entertainment and publicity purposes. These include the Girl-to-Gorilla trick found in old carnival sideshows and the appearance of "ghosts" at the Haunted Mansion and the "Blue Fairy" in Pinocchio's Daring Journey, both at the Disneyland park in California. Teleprompters are a modern implementation of Pepper's ghost. In the 2010s, the technique has been used to make dead or virtual artists appear onstage in live concerts, with examples including Tupac Shakur and Michael Jackson. It is often wrongly described as "holographic". Such setups can involve custom projection media server software and specialized stretched films. The installation may be a site-specific one-off, or a use of a commercial system such as the Cheoptics360 or Musion Eyeliner.

Products have been designed using a clear plastic pyramid and a smartphone screen to generate the illusion of a 3D object.
