While most folks would be content with giving their wife-to-be a diamond ring, some folks just want something different, and that’s probably why Luke Jerram came up with this projector wedding ring. Instead of using a traditional diamond, this ring sports a tiny photographic slide, along with a lens at the back of the ring, and when it’s lit up, you’ll see your special images projected on the wall. Apparently the light source can be small, and even a candle will work. It’s pretty cool, though it would be a lot cooler if they managed to cram a pico-projector and some flash memory into it.
