    Theres an old adage about a fool and his money. Technically speaking it can be done. There are even sites devoted to making home-made projectors but I can't see the resolution being all that good.
    example: http://www.hommie.net/index.htm
    However, the system you mention is slightly different, I think. On top of that your 27 to 36" TV now has to sit in the middle of the room to project on the wall which is an extreme pain in the ass if you have to reposition your tv just to watch on the big screen.

    Here you go...instructions located with a google search:
    Oh and if you want pictures:
    click on 100" projection tv.
    There, you owe me $10.00 [​IMG]
    100 " Projection TV Instructions
    These plans are very simple! Results may vary by types of materials you use. Works on TVs or monitors.
    These are the things you will need to make your 100" projection TV!
    Magnifying glass- Please note if it has a bifocal lens it will not work!!
    Sturdy cardboard (or fiberboard).
    Duct tape
    Black paint or paper
    3 pencils
    Small mirror (about 3"x3")(optional, you don't really need this).
    Four small washers that fit snug around the pencils.
    Step1> Measure your screen (vertical and horizontal).
    Step2> Cut the side pieces (A and B) for your projector. (Using your measurements from step 1.) Again use 35" for length. This allows the room to adjust the focus. Be sure to cut as straight as possible!
    Step 3> Cut the top and bottom pieces (C and D.) (Using your measurements from step 1). Again use 35" for length.
    Step 4> Cut out your slider (E). This piece will be the one that slides in and out of your projector! This allows for the focussing. Use your screen measurement from step 2 & 3. Then, find the center, mark it with your pencil!
    Step 5> Remove the glass lens form your magnifying glass. Set it exactly on the cent or your slider. Trace around it, and cut our the circle very carefully. Lens must fit snugly in the hole!
    Step 6> Now you have all your pieces cut. Now you either paint all pieces black, or cover with black construction paper. If painting, use more than one coat!
    Step 7> Now start to assemble your projector. Place pieces A,B,C, & D together and tape them together using your duct tape. Tape both sides so you don't get any light showing through.
    Step 8> Now connect the two side together using duct tape. Do this carefully, and now you should have a rectangular box!
    Step >9 Insert your glass lens into the hole you cut inb the slider. THIS MUST FIT TIGHTLY. It must be flush with slider. This is a little tricky, but is not impossible!
    Step >10 Take to unsharpened pencils and poke them through your slider (E) about one inch from the sides, not the top and bottom. Then put a washer on each end if the pencils. Use some tape if necessary to ensure pencils do not slide in and out! Only push a LITTLE of the pencil through, just enough to secure them. The pencils allow you to push pull the slider in and out to adjust your focus. If pencils interfere with your picture, pull them out after you have focussed your projector and put tape over the holes!
    Step 11> Place your slider about halfway in the box. Your slider must fit squarely inside the box!
    Step 12> Turn your TV or monitor upside down and carefully attach your projector. Use tape or any other way you desire! Should fit tightly and no light should shine through the box.
    Step 13> Turn your TV or monitor on and adjust your slider to focus your picture. This may take a while. The further away from the wall, the larger your picture will be! The darker the room, the clearer your picture will be.
    Step 14> If your image is reversed, place a mirror at a 45 degree angle in front of the lens. You may have to turn the screen in its back. Same principle used in school overhead projectors.
    Step 15> After the projector is setup and focussed, cut the remaining front pieces away. This allows for better viewing.
    Step 16> Have a fun with your new TV or Monitor!!!!
