A weird and quirky idea - CRT shaped glass/acrylic slab for LCD screens.

yes,yes.. cut the back from an old non-working crt, combine the methods used for making crt fishtanks and liquid lenses, you can seal the 'lens' instead of the lcd...maybe you even keep tint and front mask.

Ok, I'll be the wet blanket.

I don't think anything one tries to do in this regard will give the effect desired.  CRT images are actually painted (with electrons) onto the phosphor, which is coating the interior surface of the tube  The only way to approximate something like this would be with an LCD projector, and a curved rear-projection screen, as this is essentially mimicking the way a CRT works.  One would, of course, need to apply any scanline treatments to the image through software.  Even after doing all of that, it still wouldn't be the same, as the pixels on a CRT are actually the light source, and they are sitting only about 1/4" under the face of the screen.

A large lens might get you part way there, but it will always look like a lens, with all of the off-axis aberrations, and cost more than a real CRT.  A domed piece of acrylic would just look like you put your LCD in an aquarium.

Wait for flexible OLED panels (or whatever tech replaces it) and then go nuts :)

I was wondering about a small LED projector rear-projecting onto a light gray curved screen, using an SLG to generate the scanlines and then shifting the focus off just a tiny bit to soften the edges of the pixels, that would be an interesting effect.

In using a projector you are taking up as much room as a CRT, so what is the benefit over using a CRT in the first place?

Maximus:
Not necessarily you can bounce an image with a First Surface mirror although it will of course not be as space efficient as an LCD for sure.
