Want to create your own 3D holograms on your cell phone? If you have a CD case handy, you’re in luck. You’ll also need a few basic tools as well.
A recent Mashable article featured a British independent tech reviewer named Mrwhosetheboss who uploaded an instructional video on how to transform any smart phone into a hologram projector by measuring and cutting shapes from a CD case.
