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

This has been running around my head for a little while now and I don't even know if the physics of the idea would even work, like I said in the title it's a bit of a weird idea but...

I'm thinking of a cast piece of uhmmmmm 'clear something' that's flat on the back and has the contour of a typical CRT screen on the front. Designed to sit flat against the surface of an LCD screen and give the curvature of a CRT, I'm wondering what effect the clear cast would have on the optics, whether you'd get any nice blooming etc.

That could be quite interesting, especially if one side had something like a fresnel lens to give the impression of scan lines.

I had knocked that idea around my head several times and getting a glass maker to do something like that would cost a bunch more than getting an actual CRT screen in there.

Yeah.  Glass is damned expensive.  You would almost need a Monitor Magnifier matched with a plano convex piece of glass.  CRT's just seem to be the way to go.

I would talk to Sjaak.  In his version of Fix It Felix he made it seem as though the screen is curved.  I'm sure that someone can create a program to give this illusion.

Maximus:

Yeah there are filters that do a nice job of that. This was more of an experiment in physical approaches. Perhaps clear cast acrylic? I bout it would need to be more than about 3/4" thick
