I'd love to have the floor from a dinosaur cage. :)  Since each segment is 
pretty light the 1/4-20 bolts should be just fine.

Get an Arduino board.  They're fun to play with.

I'd need a building twice the size I have now to pull THAT particular 
trick off. :)

I'm re-thinking (again) the projector support - originally I was going to 
build a cantilevered platform that the 109F/X would actually sit on, but 
due to clearance issues, I think I might be better served with some thing 
different.  I think I'll end up with something that looks like this:

       +-------

It'll be pretty wide at the top - probably close to 72" wide due to the 
length of the projector cases.  I can put it on 4" wheels and with the 
proper amount of ballast it won't tip over.  A narrower version would fit 
in the back bay of the F-15.

For right now I'll be using a canvas drop cloth as the screen material - I 
can clip it along the top and it should hang fairly well.
