http://hisham.hm/htop/ is using video streaming for its background (actually a gif. Someone else did it, though).

At the bottom of the page:

Quote:Thanks to Alexander Waldeck for the idea of having htop itself as the page background! His page actually presents a live htop session -- mine is just an animated gif with a few frames stolen from his page. :-)

It does not looks like a real video stream, more like hacks to get TTY displayed 'live'.
