The screen is four metres high and consists of 1,440 Swarovski crystals.
Here's some text from Swarovski:
‘Veil’ by Paul Cocksedge Studio creates an incredible visual illusion; when viewed through a mirror, the shimmering curtain reveals its hidden secret: an iconic image set within the canvas of crystals, and when the viewer looks back at the curtain, the image disappears. Cocksedge sees this first edition of ‘Veil’ for Swarovski Crystal Palace as a romantic illusion.
