This cool geeky ring was created by Luke Jerram and jeweler Tamrakar for Jerram’s wedding to Shelina Nanji. Inside the ring are tiny photographic portraits of the couple. When you shine a light through the ring, it projects the images out like a tiny projector. The ring was made by hacking apart a disposable camera to get the lens. Unfortunately the ring was stolen when his house was robbed!!!!!!! Sorry Luke! So Jerram is working on a new version to give his wife.
