I don’t mean BETTER. That’s a different conversation. I mean cooler.

An old CRT display was literally a small scale particle accelerator, firing angry electron beams at light speed towards the viewers, bent by an electromagnet that alternates at an ultra high frequency, stopped by a rounded rectangle of glowing phosphors.

If a CRT goes bad it can actually make people sick.

That’s just. Conceptually a lot COOLER than a modern LED panel, which really is just a bajillion very tiny lightbulbs.

    I was thinking the other day how much cooler flap displays at stations and airports were compared to modern displays.

    Such a nice interface between computer control and a purely mechanical display. Watching them update, flipping through all the variables to land on the right one, and then clearing was so cool.

    I miss the noise they made too. Haven’t seen one for like 20 years now.
