USS Eldridge, The Philadelphia Experiment

[seadude]

I doubt this is a project I will be doing anytime in the future, but it has been on my mind because I'm curious if such a model project could be done. If so, then how?
A little history first:
http://en.wikipedia.org/wiki/Philadelphia_Experiment

If such a model/diorama were to be built by a modeler, then how would it be done?
* Special placement of mirrors to create the invisible effect?
* Special spray painting techniques and colors to get an invisible effect?
........etc., etc.

How would you do it?

Use a lot of that resin water stuff and do a ship under way but just a hull shaped impression in the water. 

The ship's invisible, not the water, but it'll show where it is.

Well, if I had the money, I'd use a large LCD shuttered monitor.  The LCD is transparent, showing the model behind it until it is then changed to slowly disappear from view, replaced by bare sea.  Need a laptop to run it.

Peppers ghost.  You set up the model in a box out of view, with a piece of glass at an angle.  If the lighting is correct, a ghostly image appears.  If you're clever with electrics you can get the image to appear and dissapear by varying the lighting.  The lighting is the key, as well as the angle you're viewing it at.

Quite effective and not difficult to do, I've seen fantasy models done using the principal.  Trouble is you need to keep external light out and that means keeping the room you're in dark, or using a small slot to view through.
