Make a 3D “hologram” using your smartphone & a CD jewel case

Create a 3D hologram illusion with your smartphone! This DIY tutorial by Arun Maini, inspired by YouTuber American Hacker, shows us how with the help of an old CD jewel case, some graph paper, a pen, scissors, an x-acto knife, clear tape or glue, and your smartphone. The illusion is completed when a specially-made four image video reflects in the transparent plastic.

Updated demo videos.

After you’ve turned your smartphone into a 3D hologram projector, turn it into a digital microscope for around $10.
