About: I have a knack for making functional miniatures. I don't use any specialized tools or materials for making these.

You will be amazed at the simplicity of this mechanism and its practicality

Use your smartphone to project 3D holographic images and videos without any modification or 3D goggles

Be mystified by images and videos popping over your smartphone!!

All this from a piece of clear plastic sheet

Step 1: Materials

  • All you need is a sheet of Clear Plastic Sheet. You can use the ones used for packing toys and stuff or even an OHP Sheet
  • A pair of scissors
  • Marker Pen
  • Clear cello-tape.

Step 2: Creating the Pyramid

Using the above template, trace out on the clear sheet 4 walls of the pyramid

Cut out the 4 walls and using small pieces of clear tape stick the 4 walls to give a pyramid shape

The tip of the pyramid here will a 1 cm square

Another Quick way is to print (with settings Actual Size) the PDF template courtesy of 1NEW GUY

all the 4 sides together, fold it to form the pyramid and stick with the clear tape.

Step 3: Projecting 3D Videos

Now navigate to YouTube and search for holographic videos

No place your pyramid in an inverted position in the center of the cross hairs you see in the beginning the video, dim the lights and see them pop up your screen

I wanted to share this video I made of an American flag and fireworks. It shows the scene from four different views, instead of the same view repeated four times. I hope all of you enjoy.

I want to make this experiment as a project for my science fair. Can you please explain me how does this work???

It works by reflecting the video on all the 4 sides, so when viewed from any side it gives an illusion of a 3D image.

Good sir, do you have any YouTube links to use with this 3D holographic art?

Simply because a company media / press release dept - nothing against arts - but of arts people where they SAY its holographic as its that nice nice buzz word - and company with management want the advance position

Dennis Gabor - not even difficult to look it up - google holography - close enough where GB patent . MIT HAVE DONE YEARS OF RESEARCH -

Had that question in Crown Court (1990 ) - the device - they wanted a holographic system - which it was not - but did not state that there was not a holographic system ""around"" ( being investigated )

Media people really should check the facts - as all scientists / engineers / mathematics required to do

Just so you know... What you've made here produces a stereogram. There's nothing holographic about the process. Holography is an interference process from laser light.

It's not a stereogram. The image you are seeing from each eye is the same. It's just a reflection. Since the reflective surface is at 45 degrees to the phone screen, the reflection appears at 90 degrees (upright).

Yep, the Instructables email called this a "holographic 3D projection pyramid" even though it is neither holographic, nor 3D, nor a projection.

It is, however, a pyramid. :)

If that's not a projection, what is it?

And what if not a reflection is a projection then?

A projection is a strong focused image on a scattering surface (like a movie screen). The image produced is two-dimensional, at the location of the surface, and may be viewed pretty much the same from many angles (just like a painting on the surface). A reflection is a virtual image created by a smooth (non-scattering) surface like a mirror. The virtual image is three-dimensional, located behind the surface, and provides a different view depending on where you're looking at it from. They are not at all the same thing, except that they both involve light and a surface I guess.

They are physically the same thing. Scattering is a form of reflection, governed by the same laws of wave propagation described by the Huygens-Fresnel principle, which states that each point of a wave front that reaches a boundary layer (at which the refractive index suddenly changes) can be seen as a point source of a spherical wave.

Thus the resulting wave is the integral of all the spherical waves.

OK, enough. If you can't tell the difference between a movie screen and a mirror, or insist on using the same words for both, then we can have no useful communication with you.

Nope... it's not even a pyramid! My Android phone tells me it's a 'frustum'. (A truncated pyramid). :o)

Good point! (And of course, it's still a cool little project!)

You're right to say it's not holography. This is Pepper's ghost.

Unfortunately, more and more people misuse the term holography for things at billion of light years of real holography.

Thank you for the great instructions and pictures, especially the diagrams showing how to lay it out on a grid and the link to template. On your grid, it looks like 1/2 cm squares, so isn't the height of the pyramid 3.25 cm instead of 3.5 cm? I imagine that might distort the image... ?
