Thanks for re-hosting it :-) I'm a sucker for "do modern things on old hardware".
Just saw a great project at Maker Faire where some guys re-purposed old WWII radar tubes to make playable video games, one of which was flappy bird.

There are CRTs with long-persistence phosphors too; they found applications in radar and the like:

The P10 phosphor there claims "Persistence from several seconds to several months"(!)

The youtube video in the article shows a very short clip of a radar screen updating. Would be cool to see one in person if there's any still around.
I just found https://tubetime.us/index.php/2014/06/09/p10-dark-phosphor-the-skiatro… too.

I had absolutely no idea that the original SoundBlaster had embedded firmware running on an 8051. It never occurred to me that our PCs were loosely-coupled piles of microcomputers all the way back then. (Now I'm off to go learn what that firmware was doing...)
Some background I dug up quickly:
