I’ve seen these on a 1950s computer too! Cool stuff. Will try to find my pictures.

I have a few vaguely similar devices, where each digit consists of a little multi-projector – one bulb per character like here, shining through a piece of film. Have seen them used on elevator readouts.

Oh man, I love that idea! I’ve been wanting to build some sort of super-ridiculous alarm clock radio, and this would be just the thing for the display – nixies (the Site 3 Thing!) are just too challenging to drive. And require a _lot_ of voltage.

I flipped this idea around in my head with the goal of eventually building an LED nixie tube. I never ended up making one, though. I did make this, though:

I brought it to kwartzlab once, did you get a chance to see it? I etched my design manually with a dremel…

The colour diffusion is really nice. I was thinking that maybe you could use a different type of cutter to play with the angle of refraction of the edge cut to get a different effect. maybe it would make the glow sharper.
