Smartphones can do just about anything. And we mean anything.

This video provides a simple step-by-step method for using your smartphone as a projector to show a hologram.

It's not very involved, either -- all you need is some graph paper, a CD case, tape or glue, a pen, a pair of scissors, a knife or glass cutter and a smartphone (of course).

After you follow the directions, you need to load a hologram video on your phone and it shows up in 3D wonder on (or over) your phone. It's definitely pretty cool.
