If you purchased double LP vinyl disc of the soundtrack of Star Wars 7, you will be surprised to see appear 3D holograms. On Disc 1, you will see a 3D hologram of a TIE Fighter and on disc 2 the Millennium Falcon. The holograms were made by Tristan Duke of Infinity Light Science Society. The grooves of the disc have been etched to reflect light so that it displays a pattern.
