I was thinking something similar, although it could be expanded to animation in general, but also... especially for an older, slower CRT display, I wonder, can the camera capture each pixel as it lights up, or is even this primitive display faster than the best cameras?
For animation, in general, what about film projectors, for example? We all know they're a series of still frames, but to see the scenes, blank spaces in between and all, well, that might be interesting, or at least pass the time.
I would love to see a high speed camera directed at a CRT tv while it is displaying video. If you can go fast enough, you could catch individual pixels lighting up as the electron beam moves across the screen. I'm not sure if we can record video that fast or not, but we should at least be able to see partial or full lines appear to light up at the same time. This would be very educational for those people who don't know how a TV works.
I'd also like to see when you shut it off. Everyone seems to be accustomed to the small flash when you turn off the television, but I'd like to see if it has a special shape or anything as it shrinks to nothing.
I've been thinking about suggesting this idea for a while. I think it's a great idea to disect the progressive scan and interlaced scan of a television perhaps. It's definately something you can't see, in process.
