Smart!

At the dinner table Wendy McLean - research scientist at Smart Holograms - dipped her hologram in a wineglass full of water and I watched, amazed, as the image on the holographic plate disappeared to reveal another beneath.

Jeff Blyth consultant to Smart Holograms, to me how they were also using holography to create a non-invasive method of testing blood sugar levels. The holographic emulsion could react to your tears – changing colour to indicate where blood sugar levels were too high. It was hoped that one day this research would be useful to diabetics. Good stuff!
