Projection TV: Have you seen those plans for the DIY projection screen? Here is my version. The futurama version was using heavy artificial brightning on my monitor (yes, using a LCD screen). However, some programs did not let me do this, such as this view of the Lion King.
Why it doesn't work well: I am using a flatscreen monitor and a fresnel lens. Monitor does not provide the brightness required, and the lense does not focus very well. However, both images are over 72" x 48"
