I still remember dragging my CRT around to LAN parties... oh the good old days... was such a pain in the ass though in reality...
Those Sony Trinitron's were literally were made of lead. My back still hurts, but the 20" was worth it!
Is there a screensaver version of this? Or a way to turn this into a screensaver?
Oh my, what is wrong with people?? Or maybe it's just me. I have a PTSD like reaction instead. I was a DVD programmer for 10 years, and every where I looked would be a screen with a DVD player connected doing this. I'm so glad to not be in the shiny round disc business any more.
As a historical note, the bouncing logo wasn't just for fun, but was important to prevent screen burn-in on CRTs. If you had a static image on a CRT for a long time, it could damage the phosphor. Sometimes you could even see the image when the screen was off! This was the original purpose of screensavers, which saved your screen from damage. Displaying a dynamic image prevented one part of the screen from being overu…
Out of curiosity, what's the physics of the bounce? Is it always angle of incidence = angle of reflection?

It feels very laggy? Definitely not running in 60fps.

As to why they are not necessary anymore: we just turn the screen off (some displays, especially OLED, are still prone to burn-in). This was not necessarily wanted in OLD CRTs, where the startup sequence could take a while (and possibly other factors, such as reducing the lifespan, but I'm not sure about this). Funnily, we are starting to see a bit of a comeback of these in OLED smartphone that have an always-on disp…
Waterloo Station (in London, named after the bridge, which is in turn named after the battle, which was in Belgium) for a while had these full colour panels which I guess may have been plasma? These were used to display train information. They suffered terrible burn-in, and I was never sure why they were used. Eventually they ripped them out and replaced them with panels using the same technology (monochrome panels m…

I think my favorite contextual example of this is the opening line from Neuromancer: "The sky above the port was the colour of television, tuned to a dead channel." Means something very different now.
I wonder if 2000n years from now, scholars will be wondering over the meaning of that sentence, the same way that they currently discuss the meaning of "wine-dark sea" in the Iliad and the Odyssey ( https://en.wikipedia.org/wiki/Wine-dark_sea_(Homer) )
If the majority of the blue you see in the world is the sky and the sea, would you just start to think of blue as a blank? If you just consider blue as something more like we consider white, then any competing hues dominate what you describe. So just like white with the tiniest bit of red becomes pink, a purplish sea becomes red?
