Make a cool hologram illusion!
This instructable will show you how to easily make a convincing floating head hologram.

It's a great addition to your Halloween decorations!
step 1Supplies
You only need a couple of things for this illusion:

1. A piece of glass.

The size of the glass is relative to the size of the area where the illusion will be viewed.


2. A monitor (and computer, of course).

Either an LCD or CRT monitor will work. CRT monitors tend to give a better reflection, but an LCD monitor can be used in a much smaller spot.

The LCD monitor I used had a removable stand. That made it much easier to hide in the cabinet.


3. Floating head movie.

I recommend Big Scream TV.







step 2Location, Location, Location
This illusion works well, but the monitor must remain out of view of the spectator.

For this instructable, I used a bookshelf/cabinet and the front window of my house for the trick-or-treaters to enjoy.

Projectors are relatively cheap these days. You could easily project the image onto a piece of glass 30 or 40 feet away. The projector would need to be located very close to the path of the intended viewer, however.

A great example of using a projector would be on an eave of your house. The glass could be suspended at an angle towards the front of the house, and then the image would be projected on it from a hidden spot on the roof. As the trick-or-treaters walked up to the house, they would be greeted with a creepy floating head on your roof.




step 3Display Setup
To keep from giving away the source of the image, adjust the brightness to the lowest setting and the contrast to the highest.

The goal is to make the background as dark as possible. Play the movie you want to use full screen, then adjust as needed.

For the cabinet configuration, suspend the LCD monitor above the viewing area. Then create a Halloweenish looking scene inside, and then place the glass over it at an angle that will reflect the image to the viewer.

For the windows configuration, set the monitor on the floor pointing up, create your scary scene, then place a much larger piece of glass over it at an angle that will reflect the image towards the window.

In either setup, the bottom edge of the glass should be as close to the bottom edge of the monitor as possible. That will make the image float in front of your scene, instead of behind it.

Adjust the angle of the glass to control the height of the floating head.








step 4Turn it on
Once it gets dark, turn it on and adjust as needed.

Once again, the camera doesn't do this illusion justice. It looks very good in person.
