Agreed,  just buy yourself a whole page magnifier Fresnel lens and stick it
over a hole in a a cardboard box large enough to cover the front of your
telly.

It's a great toy, but you either need to mirror image the original video,
flip the tv scan coils, or project via a mirror as the lens will invert the
image

Have a good old fashioned Google for DIY projector TVs 

Putting a handheld LCD TV display into a slide projector is another fun
party trick ;-)

Complete rubbish, scammers have been selling this kind of thing on Ebay for
years. http://www.100inchtv.com/ has also been around for ages.

Simply put, a standard CRT does not have anything like enough brightness to
project an image of this size.  You'd have to be in a completely dark room
to see anything, and even then it simply would not be bright enough.  You
also get quite a lot of distortion near the egdes of the projected picture.


If you can pick up a suitable fresnel lens from one of the surplass
companies cheaply enough, it may be worth trying just to satisfy your
curiosity, but it certainly won't be suitable for any serious home cinema
use.
