With a few household items and this instructional video, you can make any smartphone into a hologram projector. All you need to do is cut four trapezoid shapes from an old CD case (if you can find one!), tape the edges together, and place on top of your smartphone while a hologram specific video is playing. The images literally pop into 3D mode in the center of the plastic viewer.
So put down those boring old apps and check out this awesome DIY project after the break.
