The idea's always been frustratingly out of reach. But with simple household objects, this video shows how your phone can become a holographic projector today.
All you need is a CD case, a sharp knife, graph paper and sticky tape. Where was this on Blue Peter when we were growing up?
Simply place your projector on your smartphone, load up a hologram-specific video, lower the lights and watch the images leap off the screen. Smartphone holograms have never been easier!
