Designing the Ghost House

Designing the Ghost House

In the posting I did about the dolls house that we are building I mused about whether or not it could be automated to give the appearance of people or things living inside it.

Since then I thought a bit more and I think its entirely practical that such a thing could be done and the diagram here gives an idea or two.

First up is using puppets - or automata - to give some motion to it. The mechanism can be hidden in the roof or floor - depending if they work by string or wire. Here you can see a ghost coming down through the floor and another skull making the same trip. Although these are shown using cranks, intact Id probably use small servos or stepper motors to allow them two be moved individually. While the romance of brass cams and steampunk mechanisms appeals, using electronics gives more control and would allow interaction between the ghosts and the viewer in a less predictable way.

The last ghost, sitting bottom right in a chair is a variation on peppers ghost a victorian illusion that I keep find now days being referred to as a hologram  - its not. Its a simple partial reflection that unless done live isnt even stereoscopic. In the use of the effect above, the originating image is a LCD screen built into the floor. You can see the reflective glass at 45 degrees and the ghost will apparently sit on the chair or move around.

I dont suppose I will ever build this, at least not in this form; but it was a good think through and design.I also quite liked the drawing that I did - at the moment Im still into grunge and imperfection in a big way.
