I had no idea this was even possible!
But it's apparently true: you can cut a vinyl record in such a way that, when viewed from the right angle, you can see a hologram hovering over the surface.
Disney is releasing a 2-vinyl record collection of music from Episode VII: The Force Awakens. When you play them on a turntable, you can see either a TIE fighter or the Millennium Falcon.
If Disney releases a third record this way, I hope it puts on it the Leia hologram from Episode IV.
