Can't figure out what you guys are talking about. I have a plasma TV that's as big as the sun. No static, although yesterday I mistook the sun for my set; so no matter how clear the view was, I can no longer see it. Oh well, speaking of The View, yeah, at least I'll never have to see those bitches again. So on the bright side, there's that!

There's your TV static without the sound. I tend to keep my tv muted when it's got static on it, so this is what mine looks like.
That's awesome!
I guess the sound could just be white noise created with the updated sound command.
It's a little uniform. If you look at the above videos, and keep your eyes on the screen, one of them has this effect where certain pixels seem to stay lit a little longer or "float" on top. The third video is the most interesting, it's not just static but these patterns appear, as if the horizontal control on the set is drifting. That would also be interesting - simulating the "horizontal" control changing on an analog TV set.
Anyway, thanks for that bit of code, I could see that being a neat little effect in a game where you have a simulated analog TV.

Ha! Back in the Reagan years, I made a couple games on the C64 (or were it the TI99/4A) for an explosion effect.
I soon realized that staring at something like that was making my ears pop!
I think a real explosion, a single split second flash of white is more realistic.

Pretty cool!
Gets a little painful to stare at... I was looking for something a little smoother.
I'll get something working soon I hope, if the distractions don't keep happening!

You poor child! You must be reading this on a Braille computer display (I imagine those must really exist?)

That would make a cool background for a quasi-3D space invaders type game, with the tunnel taking some twists and turns, and the player needs to steer to avoid the walls as well as shoot the aliens...

" Braille computer display (I imagine those must really exist?) "
Yes they do and have existed for a very long time. Back in the early 90's when I was a computer tech I serviced a blind person's system at a local bank. He was a loan officer. He used a combination of a Braille display and optical hand held screen reader. The Braille display would bring up a line of text as he panned the optical reader over the CRT. It was quite cumbersome to use but he made it work. I imagine today's systems are much more sophisticated.
" Impressive! "
I agree, those animations are awesome vince!
There are two ways to write error-free programs; only the third one works. QB64 Tutorial
