rotationally symmetric rectifying mirror; anyone know who ..

Archived from groups: alt.tv.tech.hdtv (More info?)

My house I'm now renting has concrete walls and I cant run cables through. I
want one of these mirrors so I can setup a system like seen here:

Actually with projector and mirror located below the screen. This type of
mirror would allow me to shorten my throw distance greatly. my equipment is
NEC MT1050 and a 100" 4:3 screen.

My other option would be a flat, top reflective mirror at 90 deg in center
of room and projector placed on side of room.

I cant ceiling mount and I want to avoid center table mount because of
cabling.
