If you feel like having some friends over and wowing them with your technological wizardry we have a treat in store for you.

A fellow by the name of Mrwhosetheboss has done the hard work, and we’re not going to argue with that name because this is one pretty nifty little trick. Sure you’re not going to project a life-size replica of Justin Bieber onto the wall – and if that’s why you’re here please exit via the red cross in the top right corner – but get this right and I’m sure you will earn some serious brownie points. Below from Huffington Post:

Here’s what you need: graph paper, a CD case (you’ll have to get rid of them one day), tape or super glue, a pen, scissors, a smartphone and a knife or glass cutter.

To build the projector, draw a small rhombus on the graph paper, use that template to cut out four rhombus shapes with the plastic from the CD case, tape the four plastic cut-outs together, place the 3D construction over your smartphone, load up a “hologram-specific video” (like thisone), press play  — and voilà! A homemade hologram!

You can increase the size of projector’s rhombus teplate as much as you like, Mrwhosetheboss noted, as long as the projector fits atop your smartphone screen when you’re done.

We welcome any user submissions or accounts of how this went down at home. Better yet, why not try it in the workplace and waste a few hours while you’re at it?
