Turning your smartphone into a sort a budget holographic projector is much easier than you'd expect, and it's a fun Monday project if you find yourself bored today. You'll only need a few things, and the above video will show you the entire process.
I'm going to warn you a bit, however, that cutting the plastic is trickier than it looks, and it's very easy to slip and cut yourself. Proceed at your own risk, and perhaps lock up any cats or children for a few minutes.
This optical illusion has been around for a very long time, but using it in this manner to sort of emulate the look and feel of a hologram is a cool idea. Enjoy!
