A tube to make a black & white tv color

Hey wasn't the transistor discovered at the Roswell crash site? Not sure if I believe that one, but I digress.

Do they make a tube that can make an HDTV display SD without smearing and pixellating? If so I want it!

You can make such a tube:

Take a hollow tube (a paper towel roll core will do), attach a concave lens (aka negative lens) at one end, and a convex lens (positive lens, magnifying glass) of equal value at the other.

Now face the concave lens end toward that 56" plasma, and watch TV by looking into the convex lens. Your SD picture will be pinsharp, and you won't notice any pixellation.
