Stereoscopy is a Victorian technique for creating an illusion of depth in an image.
At its simplest, it involves viewing two images side-by-side that through a special viewer which turns them into a 3D image.
At one point during the late 1800s it was a worldwide phenomenon – bringing virtual reality-like experiences of world-famous locations and people into millions of homes.
But it has gradually waned, especially since computers and video games brought a different kind of ‘reality’ to our living rooms.
Now Queen’s Brian May, inspired by his own childhood experience of taking 3D images, wants to bring it back.
