I tried to build the projector from those very same plans, and I have nearly completed it. The last element to get is the 5" LCD, which is harder to find than you might think (and hard to find CHEAP)... anyway, the idea seems sound, I even tested it by ripping the LCD out of a $2 calculator and shining a flash light through it. However, never finishing the projector I cant say as to how well it actually works... sorry.
