Here is my reply to Joobs

Thanks Joobs.

- 1/2 inch acrylic sheet.
- thin layer of silicone [using rockit advices - http://nuigroup.com/forums/viewthread/6/P75/]
- mylar on top.

I don’t really understand what you mean by “even if it’s tapered at the back.” ...
Is that about where the projector and video cam are ?
If so… they, for now, are simply facing the acrylic [with an angle of almost 45]. The final plan is to use a mirror and include the projector and cam in the box.

From those pictures you posted, the table looks like it’s half a foot deep.  So are you saying the projector and camera are just mounted on the floor/wall pointed at the table?

yes exactly.

As the table top rotates, I will need to find a way to include the camera and projector in the wood box.
The projector and camera would need to be installed in a way that it will easy to switch from the table at a 45 degree angle to 0 degree.

any idea are for sure welcome ....
